6. Too Much Inter-Referencing
I never thought I'd say this, but the Marvel Cinematic Universe stuff is beginning to struggle under its own weight and it's becoming difficult to watch movies in the canon as a result. And trust me: you won't find anybody else out there who gets quite as giddy at subtle inter-references, characters showing up in other movies, and meta-gags as I do, but the Universe is beginning to feel a little strained, caught between trying to make every moment an "individual" entity, whilst still trying to appease those who crave nods to the MCU. Case in point: Thor: The Dark World feels static and almost lifeless, because it knows it can't really be a movie in its own right - it has to play ball with the other movies in the MCU canon, which - when you think about it - is a totally bizarre way to make a film. When we first got a glimpse of Tony Stark chatting with Nick Fury about the Avengers in that post-credits sequence, it was exciting - but now there's so much emphasis on trying to build up to the next "mega movie" (i.e The Avengers 2: Age of Ultron) that the singular entries just feel like personality-less placeholders. In a weird way, pretty much all comic book movies have become about "the next one" - filmmakers (or more likely the producers) are so fixed on what they're setting up for the next billion dollar flick, that there isn't enough of an emphasis on each movie as standalone story. It used to be great fun; now it feels like added pressure.
