Agents of S.H.I.E.L.D. was Marvel's next-step move to extend their cinematic universe to television - and to say that the ride through season 1 was volatile would be an understatement. For the first half of the season, it was not looking good; the general consensus was that the show was not on part with the Marvel cinematic brand. However, after the game-changing events of Captain America: The Winter Soldier, the show found a foothold and managed to regain some fan confidence on its way to the season 1 finale.
Of course, Agents of S.H.I.E.L.D. season 2 has some lingering mysteries to confront - including the origins of serum GH325 and the blue man, what the serum means for Coulson and Skye, and what S.H.I.E.L.D. actually is now that the organization has come apart at the seams.
Thanks to the Agents of S.H.I.E.L.D. Facebook page, we now know that season 2 will premiere on Wednesday, September 23rd, having shifted from the Tuesday night slot occupied by season 1 to make room for new superhero TV shows like The Flash. Indeed, fanboys and fangirls are going to be quite busy in this new TV season, with Arrow, Constantine, Gotham and the Agent Carter spinoff series all airing (to name a few).
For Marvel fans, it's going to be interesting to see how the cosmic-set Guardians of the Galaxy affects the show (those extraterrestrial connections are more and more apparent), as well as how AoS season 2 sets up premises for films like Captain America 3 and/or The Avengers: Age of Ultron (which could feature Coulson's S.H.I.E.L.D. team). Beyond that, it's not a stretch to say that most fans are probably just hoping for a better, smoother experience than they got from the early half of season 1.
As stated, Agents of S.H.I.E.L.D. season 2 will premiere on Wednesday, September 23rd.
