A solid cast compliments great writing and special effects in this movie. The storyline was close enough to the original book to please even the most die hard of fans. I was excited about Downey playing Tony Stark, because i knew he could pull of the comic book version of the character, and he did not disappoint. Special effects were good enough to add realism to the suit. Generated graphics were not over done. I saw this movie on early premier Thursday night. This was very very good. Can't wait for the sequel.
