Well that was awesome! It's Marvel. What more is there to say?
The plot may be a bit too character-oriented, riddled with self-doubt and relation-breaking mistakes by superheros you'd have thought had better traits, and it was all but as massive as the last Avengers movie, but I guess part of its greatness lies in that contrast, and in not always going the way you expect it to.
It doesn't go the way Stark expects it to either, and one of the more brilliant moments of the movie is one of those parts. The personalities and ties between characters really come into the open on this one. If you thought their collaborative capabilities were great before, you should see them now! They're... not so.
On a more superficial level: it's awesome to just see the heroes duke it out among themselves. This one time they themselves are their main adversaries, and maybe they always will be? After all, to surpass yourself is always the goal, and to put your faith in someone else means making them a part of you. Sort of.
The special effects are top notch. It's packed with emotion. Packed with action too, and an intrigue that twists easily. We get a couple new heroes on our hands as well, and one unconventionally normal villain.
Political interference in the Avengers' activities causes a rift between former allies Captain America and Iron Man. And then, an innocent man dies, an all but innocent man is cast with blame, a new hero (or is he an anti-hero?) appears, and the Avengers expand, and yet at the same time their divide goes even deeper. It's a rift that seems difficult to rise above, but I'm sure there'll be a sequel to tell us if they do. As always with these movies, it was pretty awesome.
