Just so we're clear: I am a comic geek from WAY back!
So I was very excited about the 1st Iron Man movie, though I was skeptical of Robert Downey Jr. playing Tony Stark. Watching him bring Tony Stark to life on the big screen was a joy to behold. Jon Faveraeu and Co. made Tony Stark's world feel like something that could happen in the real world. It was very believeable.
The second movie builds on the 1st and is even better than its predecessor. Outside of the returning cast of characters, (excluding Terrance Howard, but including the very talented Don Cheadle) Scarlett Johansson smoldered as Natasha Romanov/Black Widow, Sam Rockwell played Justin Hammer to smarmy perfection, Mickey Rourke, fresh from "The Wrestler", was dangerous and sinister as Ivan Vanko/Whiplash and Samuel L. Jackson owned the screen as Col. NIck Fury.
The stakes are raised as Tony Stark is dying from the Palladium in the Mini-Arc Reactor, the very thing that saved his life in the 1st movie, while competitors and the Government want him to turn over the Iron Man armor. There are some Daddy issues for Tony as well and we get to see how even a man as boudlessly confident as he could be made insecure by the genius his father displayed.
I'm not going to give away the story, but there are some cool scenes: The fight between Iron Man and War Machine, Whiplash's first attack on Tony at the Monaco Grand Prix, The fight scene with The Black Widow and Happy Hogan and watching Tony Stark build a particle accelerator in his basement.
Iron Man 2 will be a delight to hardcore fans of the comic books and to those who came onboard with the first movie. Trust me, a good time will be had by all. (In Meredith Grey Voice)Seriously? Seriously.
