As Thor says, it is better to "be a good man than a king." Also, sometimes the meanest of people can redeem themselves.
Loads of explosions, knife fights, and gun fights, though the results aren't gory. A woman slaps two men out of anger. Intense battle scenes where entire landscapes are obliterated. Characters shoot, stab, and kill each other, but again there isn't a lot of blood shown.
Some kissing and flirting. A man is shown on a TV newscast running around naked, but not in a sexual context; his privates are blurred.
A few instances of "shut up," "hell," and "holy s--t."
Part of the Marvel universe, which has tons of merchandise associated with it.
Some revelry involving drinking.
