While the film isn't quite
what I expected (the Extremis soldiers and the Mandarin twist primarily), I really enjoyed it. I'm sure I'll enjoy it a lot more in repeat viewings once I accept what the film for the story it told, and not for the story I thought it would tell. All that aside, I nonetheless loved the twist in regards to the Mandarin and I know a lot of hard core fans are going to be pissed (kind of how I felt with all of the Spider-Man
Lots of great humor, character building (great character study for post-Avengers
Tony), action sequences, great use of the entire cast (from Paltrow and Cheadle to Pearce and Kingsley as well as the unexpected appearance of James Badge Dale), and unexpected turns in the story. The Extremis soldiers aside, about the only thing that really bugged me about the film was the absence of Harley's mother. Where was she? Surely she was concerned that her son was hanging out with someone who could put her child in danger. A minor, but persistent quibble.
The falling passengers sequence was incredibly intense and I expected only four people would survive (despite what the trailers had us believing), although I'm sure the way survived wasn't actually possible. But who cares? This is a film about a guy who fights and flies around in an armor suit.
Edit: I loved the post-credits scene with Mark Ruffalo reprising his role as Bruce Banner, especially considering I expected Tony talking to an annoyed Nick Fury. Speaking of which, I was surprised Samuel L. Jackson didn't make an appearance. While from a story standpoint, it's better for the film not feature Fury, this is the first Avengers
-verse film not to feature Jackson (aside from The Incredible Hulk
which does and doesn't count).
