I'm behind on my listening so apologies for that. I agree with you guys 100% on Iron Man 2. From beginning to end, I absolutely loved this film. Like you, I don't understand the fan backlash even one bit (but then again, I didn't get the backlash to Hulk and Superman Returns).
In regards to the continuity with The Incredible Hulk, Favreau said that Iron Man 2 actually takes place before The Incredible Hulk. Some pretty poor planning on that front, but that's the explanation.
And for the record, I did indeed go "yes!" at the Oldboy comment.
