It's hard to believe that only a few years ago, the idea of a superhero TV series was pretty unusual, and that Arrow was the only major DC/Marvel series on the air (in live action). Arrow took advantage of the huge success of superheros on the big screen, bringing a lesser-known DC hero to TV: Oliver Queen, a.k.a. Green Arrow (Stephen Amell). A relatively straightforward origin story, Arrow told two parallel tales: Oliver's time 'on the island', and his life after he returned to Star City to become a masked vigilante.It was a fantastic concept, helped in no small part by the stunningly handsome leading man, and one that quickly gained popularity and success. With Arrow doing so well, the CW expanded their DC TV universe, adding the spin-off The Flash, quickly followed by Legends of Tomorrow. In addition, the network took on Supergirl after a poor first season on CBS, folded the character of Constantine (Matt Ryan) into the Arrowverse after that series was canceled on NBC, and has now picked up Black Lightning, a series originally intended for Fox.Related: 16 Things Everyone Gets Wrong About Green ArrowIn many ways, it seems that the Arrowverse can do no wrong, as it continues to expand, win awards, and pull in viewers... but the show that started it all is no longer the jewel in the DCTV crown. Instead, Arrow has been slowly losing viewers and recycling old stories... and with the Arrowverse growing every season, it's time to retire Oliver Queen and create space for something new.

The First Five Years

A lot of the current issues with Arrow come down to the simple fact that the original premise has been wrapped up, and it doesn't know where else to go. The first five seasons of Arrow charted Oliver Queen's journey to becoming a hero - both his training on the island (and off it), and his forays into superhero-dom in Star City. It was the kind of origin story that fans loved, but with that wrapped up by the end of season 5, Oliver is left without many places to go. Now Oliver is an established superhero in Star City, with an ever-changing team behind him, and his identity has been revealed to everyone that he loves.

A lot of the tension of the first five years came from surprises: the reveal that Oliver wasn't actually on the island for the full five years, the moments where his loved ones discovered his identity, the will-they-won't-they dynamic between Oliver and Felicity Smoak (Emily Bett-Rickards), the deaths of major players... all things that have now been essentially dealt with. The other major change is in the viewers themselves; at a point in time where there was no contest, Arrow was fantastic simply by being a superhero show. Now, with heroes bursting onto the screen on every network, and multiple new heroes joining the ranks of the small screen every season, simply being a kick-ass hero isn't enough to keep Arrow alive.

Arrow Has Lost Its Edge

It doesn't seem like Arrow is going to be able to re-gain the success of its early years. Oliver's origin story has been well and truly told, his family members have all been explored (and his secrets revealed), and we're left with a show that has started to become extremely repetitive. Season 6 has already seen several old storylines trotted back out, and it's simply no longer thrilling. Oliver's identity is revealed! Diggle (David Ramsey) has to take his place under the hood! A teammate has betrayed him! He doesn't totally trust his team! There may be a new big bad on the horizon, but so far, season 6 has been extremely stale.

Oliver continues to make the same mistakes - mistakes that should have been resolved through the Prometheus storyline in season 5. His relationship with Felicity is also bordering on boring, as it's only really possible to have so many break-ups and make-ups before fans just start rolling their eyes at the whole thing. While it's still exciting to see Team Arrow join forces with the rest of the Arrowverse in the now-annual crossovers, these are now the high points of the series - as the ratings prove. Arrow saw a 29% drop in its overall season 5, followed by a further 17% drop in ratings for season 6 so far. However, the crossovers marked a season high for Arrow, with a whopping 200% rise for Crisis on Earth-X... even though that's still a 31% drop from last year's crossover episode.

Time To Ride Off Into The Sunset

Although we already know that Arrow has a seventh season on the way despite falling ratings, the series really needs to wrap things up with that season - and an eighth season is simply unnecessary. At this point, Oliver's story feels complete, and it's time for him to (finally) marry Felicity and settle in with her and William (Jack Moore). He's increasingly finding that he can clean up his city through his work in politics - something that he will risk losing if he continues to work as the Green Arrow. His most recent team has separated, and bringing in another new team starts to make Arrow seem not just repetitive, but cluttered. Oliver has learned his lessons, and it's time for him to hang up the hood and move on.

The seventh season provides the perfect vehicle to wrap things up, as well. Season 6's ensemble of villains and his recent issues with the team seem to be guiding Oliver toward the long-overdue realization that he cannot continue to try and be the biggest hero in Star City; it's time to pass the torch. Season 7 could be a perfect farewell to Arrow, as Oliver and Felicity get their happy ending, as the other heroes of the city take their rightful places out of the shadow of the Green Arrow, and the lessons that Oliver has learned are cemented as he says goodbye.

Aside from the argument that Arrow needs to wrap up or risk becoming a bore, there's another reason that it's time for Oliver Queen to step down - he needs to let other heroes take his place. The Arrowverse has started to grow to an unmanageable size, with five separate series over three worlds (Supergirl and Black Lightning both existing separate to the main universe, in different ways). Fans want to see more characters brought to life, more diverse heroes, more teams led by women and POC, but if none of the existing shows are canceled, the Arrowverse will become too crowded to sucessfully manage that.

The best option would be to allow series like Arrow to bow out, so that new, more original series can take its place. In the same way that Legends of Tomorrow has a rotating ensemble cast to help the team dynamics stay fresh (and allow for deaths with real impact), the Arrowverse as a whole could benefit from some rotation; older or less unusual series replaced by more novel offerings or lesser-known heroes. The existing heroes of Arrow would still have the option to pop up for cameos and the massive crossover events that fans love, but don't need to have full seasons once the core story is told.

Who Could Take Oliver Queen's Place?

Should the CW decide to kill off Arrow after season 7, there are some fantastic options for new series to take its place. One option is to create another direct spin-off with an existing character, like Black Canary (Juliana Harvaky), whose portrayal in Arrow so far has been a major disappointment to fans of the comics. Canary could also open the door to a Birds of Prey series; a female-fronted team up that could have a very different feel to Supergirl, the CW's other female-fronted super-show.

Another option would be to make good on all the Green Lantern Easter Eggs that the series has dropped over the past six seasons, and finally introduce some of the Green Lantern mythology to the Arrowverse. The Hal Jordan version of the character already has a long-standing bromance with Green Arrow in the comics, as well, which would mean a Green Lantern introduction in season 7 would be a perfect opportunity for a little comic fan-service, and would leave plenty of space for future team ups.

Of course, it seems that despite the falling ratings, Arrow is still enough of a success for the CW that they may continue to force the show to continue until it becomes utterly untenable... but we're hoping that that's not the case. As the show that launched the recent wave of superhero TV, Arrow deserves to have a proper send-off, and not a slow and painful death.
