I enjoyed this movie but be warned:

It's a look into the tidy and ordered mind of Tony Stark as he suffers a slight anxiety attack.

Lots of action, lots of iron men, lots of "where the hell did that come from?" and strangely I can ask of some characters "Are these characters more than unthinking rocks?"

This is more of a fit inside the MARVEL universe of comic books (or more elegantly - graphic novels) because those stories are always disjointed and never a straight path from a to z.
