I found this "The Good, The Bad and The Ugly of Iron Man 2" article written by The Playlist Nation crew a pretty entertaining read. They break down a lot of the points that I brought up in my head while watching it earlier today.
And by the way, it's not that bad - Iron Man 2 that is. It gets off to a bad start and Mickey Rourke is a lame villain, but in the end, although a sizable step down, it half-works to avoid a serious pitfall. Full review later on.
