Not the Greatest.

The first one was, by comparison, the greatest, at least thus far. The second one seems hollow.

It does have it's moments, but it's in what it has failed to do that is really the films downfall.

Stark is a narcissistic alcoholic. That is the fact of his character in the comic books and probably why Robert Downey Junior was chosen for the role.

They touched on it in Iron Man, the touched lightly on it in The Avengers. Iron Man two has it as sort of a focus, but rather than making Stark the flawed character, or even as a driving part of the plot, they give him an illness to inspire a YOLO effect as an out.

The movie suffers for it, as a whole. The illness is a cheap sub-plot that was substituted for real demons.

Instead of bringing him over that hill, they never let him cross it, they never let him grow stronger for the experience.

As a result, you have a decent enough plot with a gaping hole of cream-filled uselessness in the center.

Looking back, it's not a bad movie, it could have been great, it just lacked the brass to go there.
