Man, I don't know what people are expecting out of a big budget Marvel movie. In the 2 hours and change that happened, there simply isn't enough room to fit everything in. These movies are of excellent quality when you compare them to most anything else in the box office besides a few rare exceptions. Marvel has produced the best super hero movies to date and they'll only be getting better, I can promise you that. That being said, the bit in the train was just absolutely awful. I hated it. Physics in the rest of the movie aside, that was so dumb.
