I am a huge Marvel Studios fan, and enjoyed in some fashion the 5 movies that led up to this one. The beauty of character development being taken care of in other movies allows Avengers to delve right into character conflict & action! Sure, the story is simple, but the acting, dialogue, action, and comedy are top rate. I was so worried about Avengers being a complete flop due to the enormous hype it produced. But I left the theatre with aching hands from gripping the seat handles for so long. I grew up reading Marvel comics, and I can only hope Marvel Studios does a similar thing with Fantastic Four, Spider-Man & X-Men. Great job, Marvel. I can't give it 5 stars only because the story wasn't complex enough. But definitely a 4.5.
