Edit: And before some comic fanboy goes off his rocker, yes, I'm aware of the historical comic linkage between Iron Man and the Avengers. I just don't see the need to adhere to canon, and think the as-envisioned movie Iron Man works better alone.
Okay, but...
1) There was Avengers "cross-over" material in the first one, and...
2) They've been pretty open from minute one about the fact that the various marvel movies--both Iron Man movies included--are leading up to an Avengers movie.
Nothing wrong with you feeling the way you do, but you should, at least, have expected it going in.
