I believe Marvel's time is coming. The end of the road is fast approaching for them; they've had a run of great movies, really great movies: Thor: The Dark World was fun and light-hearted, Iron Man 3 was surprisingly peppy in between the serious moments dealing with Stark as a human being, and Captain America: The Winter Soldier was one of the most solid spy thrillers I've seen in a long while.
But we're now entering the decline of the Marvel movie. We have peaked. And I can tell you that with complete confidence. No other Marvel movie will ever again be good. Because Avengers: Age of Ultron just set the God damn gold standard.
