Out of interest, how would you rank the other Avengers movies? Interesting that you say that you wanted it to be more like Iron Man 1 AND 2, since I know there were a lot of people who were really disappointed with Iron Man 2.

I'd put the movies so far as follows:
1. Avengers Assemble
2. Iron Man
3.= Iron Man 2
3.= Thor
5. The Incredible Hulk
6. Captain America: The First Avenger

But yeah, I'd still really recommend "Kiss Kiss Bang Bang" if you haven't seen it already.
