I loved it!!! It's definitely on my Christmas list this year!
At first, I thought that the makers were crazy for hiring Robert Downey, Jr. for this. But after seeing the way that he played Tony Stark, I can't imagine him being played by anyone else.
Can't for the sequel! BTW, they're going to re-release "The Dark Knight" in theaters next month, even though it's coming out on DVD/Blu-ray next week! They're hoping that it will outsell "Titanic".
