I have now watched Iron Man I'm I'm afraid to say...
It totally rocked!!!!!!
The casting was excellent, I loved the plotline and sure you'll have loads of people nagging about plotholes and such nonsense, but as a casual viewer I didn't see any that stuck out to me so ... who cares.
I was worried beforehand that they'd spend too much time on Tony's playboy ways, but thankfully they didn't. I'm also happy that they didn't try and make an actual romantic relationship between Tony and Pepper. Those two work much better as friends, than they would as lovers.
Tony and Rhodey on the other hand... I loved every moment with those two.
In short, loved the movie, can't wait to see it again and buy the dvd.
