Movie sequels are never a guaranteed thing. Just because audiences ate up one movie doesn't necessarily mean they'll accept a second. Some movies lend themselves well to sequels, especially those movies that need to expand on their stories or worlds, but some don't. Many movies are just fine remaining single entities, and audiences can see right through the studios when they attempt to capitalize on a one-and-done experience.

If this decade will be remembered for anything, it will be it countless reboots, remakes, and sequels. While some were fantastic, many were utter failures. These are the ten biggest sequel box office bombs of the decade, according to box-office mojo.

The Girl In The Spider's Web - Lost $8 Million

The Girl in the Spider's Web somehow serves as a sort of soft reboot and a sequel to The Girl with the Dragon Tattoo. Such is the state of mainstream Hollywood in 2018.

The movie was given a very modest budget of $43 million, Claire Foy was cast in the lead role, and Dragon Tattoo grossed over $230 million. This thing should have been an instant home run. However, it received very middling reviews and grossed just $35 million at the worldwide box office, a roughly 85% drop from the first movie. Sorry Claire, but this was not a good choice for your first leading role...

Terminator Genisys - Lost $10 Million+

Absolutely no one was asking for another Terminator movie, but this is the 2010s, and if there's one thing we've learned over the years, it's that the studios have a tendency to milk franchises until they're dry and shriveled.

Despite a budget of over $150 million, Genisys looked absolutely horrible, which certainly didn't help the film's legacy. The PG-13 rating didn't help, either. It grossed just $89.7 million in North America and $440.6 million worldwide, and Bloomberg estimated that it needed to make $450 million just to break even. Despite this, they wanted to give the franchise one last hurrah.

Sin City: A Dame To Kill For - Lost $25 Million

Was anyone asking for a Sin City sequel? And even if they were, maybe it should have come out sometime around 2007. You know, when Sin City was still fresh. Not nearly ten years after its release.

Despite a rather meager budget of $65 million, A Dame to Kill For was dead on arrival. It grossed just $13.8 million in North America (yes, $13.8 million) and $39.4 million worldwide. It was a monumental disaster. But then again, this thing was doomed for failure from the start. Seriously, what were they thinking with this one?

Justice League - Lost $60 Million

The Justice League movie should be studied in film and marketing courses. Not because it's good mind you, but so we don't repeat the failures and mistakes of our past.

Justice League was supposed to be The Avengers of the DCEU and was given a certifiably massive $300 million. It should have been the movie event of the decade. It ended up grossing $657.9 million, which is a pitiful amount for such an event blockbuster. This thing should have made billions.

In the end, the break-even point was estimated at around $750 million, and the movie may have lost Warner Bros. up to $60 million.

The Huntsman: Winter's War - Lost $75 Million

If there was one movie we were all clamoring to see more of, it was Snow White and the Huntsman. So 2016 came along and we got The Huntsman: Winter's War.

The first movie grossed nearly $400 million, so the sequel was given a budget of $115 million. However, it received just 18% on Rotten Tomatoes and opened to $19.4 million, a 64% drop from the original's opening weekend. It ended up grossing a laughable $165 million (including a pitiful $48.4 million domestic return), losing Universal up to $75 million.

Teenage Mutant Ninja Turtles: Out Of The Shadows - Lost $75 Million

Serving as the sequel to 2014's Teenage Mutant Ninja TurtlesOut of the Shadows was granted an enormous budget of $135 million. It makes a certain kind of sense, seeing as how the first movie made nearly $500 million. However, it seems like no one was really clamoring for a sequel.

It grossed $35.3 million in its opening weekend, which was down 45% from the first movie. This was prophetic, as this movie made less than half of the original's gross, scoring just $245.6 million. It failed to find an audience and ended up losing Paramount up to $75 million.

Blade Runner 2049 - Lost $80 Million

Blade Runner 2049

Blade Runner 2049 is a fantastic movie, but that doesn't mean it wasn't a box office bomb. The movie was enormously expensive, costing the studio anywhere between $150 and $185 million to produce. It was a huge risk, especially considering the three-hour run time and the fact that Blade Runner was released back in 1982.

The returns were disappointing, as the movie grossed just $92 million in domestic markets $168 million internationally for a combined total of $260.5 million. The break-even point was estimated at $400 million, and the movie lost Warner Bros. roughly $80 million.

Transformers: The Last Knight - Lost $100 Million

Transformers is so 2000s with 2014's Age of Extinction being an enormous success, grossing over a billion at the worldwide box office. But something clearly happened between 2014 and 2017, because absolutely nobody seemed to care about The Last Knight.

It opened to a laughable $44.7 million (despite projections going as high as $75 million) and ended up grossing just $605 million at the worldwide box office. It was another major dud for Paramount, who lost upwards of $100 million in the disastrous ordeal.

Dark Phoenix - Lost $120 Million

Dark Phoenix served as the twelfth installment of the X-Men franchise and the direct sequel to Apocalypse. And if Apocalypse was disappointing, Dark Phoenix was straight-up abysmal.

With an astounding $200 million budget, the movie needed huge legs to succeed and make money. However, it opened to just $32.8 million and debuted behind The Secret Life of Pets 2. Now that's just sad. It ended up grossing just $252 million, and Deadline Hollywood has estimated that it lost Fox up to $120 million. Now that's what industry experts call a total dud.

Terminator: Dark Fate - Lost $130 Million

If there's another thing the 2010s taught us, it's that Hollywood isn't above shamelessly reaching into the past to please the present. In this case, that included wiping everything but the first and second movies from existence and bringing back Sarah Connor to the Terminator franchise. However, their desperate attempts didn't amount to much.

The disastrous movie was given a budget of $185 million and needed upwards of $480 million to break even. However, this movie performed even worse than its predecessor, grossing well shy of $300 million. It will lose Paramount $130 million. Time to terminate this franchise already.
