Wow. I can't remember the last time a saw a movie and felt like when I left the theater it was my first full breath in 2 1/2 hours! Every character was well written and well acted. There are enough positive reviews out there so I'm just going to say go see it, even if "comic book" movies aren't your thing. Remove the costumes and this is just a great crime drama. I'm going to have to check it out in IMAX next. Oh, and see it before you take children and judge for yourselves if you think they can see it. It is very intense.
I was going to title this great superhero movie, and it is, but I think even those who might not enjoy the genre will still like this movie. Robert Downey Jr. owns this character! Tony Stark is Money (thank you Mr. Favreau)! I thought everything worked from the humor to the action/CGI and even the nods to comicbook fans. I will see this multiple times and buy the DVD. I can't recommend this enough... a lot of fun! Go see it!
