Very nice action combined with good humor and story

Rating: 10/10 (11 May 2013)

This has become my favorite of the Iron Man movies.
I liked it because: Good story about Tony Stark himself. I loved that they made the character human enough to encounter struggles such as the post-traumatic stress after the encounter with Loki and the aliens in The Avengers. It made for a far more compelling character then if he was simply able to shrug everything else off like Superman - he would have been far less relatable. His interactions with the kid are interesting, especially in light of the revelations about Tony's own strained relationship with his father in Iron Man 2. Some complain about Tony Stark dominating the screen over the Iron Man character - I actually liked that. I found the Stark part of the character more compelling. His relationship with Pepper was also continued with a satisfying story arc as well.
The twist. Many didn't like this, particular the hard core comic book fans (I'm not a hard core fan, more like very light to casual, and it will likely remain that way). I loved the twist. I liked the storyline with Killian and his scheme and found it more interesting than where they had seemed to be going with Ben Kingsley's Mandarin. That being said, I do think both Guy Pearce and Kingsley both did fantastic jobs in their roles.
The humor. Again, there were those who complained about it, but their tastes are very different from mine. Personally, I choose not to be uptight about movies, especially in a fantastical genre as the superhero movie. The humor not only makes the movie enjoyable (and I am not going to watch a superhero movie with the intention of seeing The Godfather or Citizen Kane - no, I go those types of movies to be entertained, as do many of the movie-going audience), but the humor also makes everything seem more human/real as well. The humorous moments were very welcome (and also adds to the likability of the Tony Stark character and the cast in general.)
The cast. In addition to Robert Downey, Pearce and Kingsley, the rest of the cast are great. Don Cheadle is a welcome presence as Rhodey, Gwyneth Paltrow's chemistry is good with Downey and James Badge Dale is a menacing presence as a henchman.
To sum up, the movie is great if you like action,humor, and story and aren't caught up too much into a perception of how certain characters should play out. That was the case with me and I enjoyed the movie immensely.
