good back-story, and good acting

It was OK. I don't see why everyone loves it so much. It wasn't very smart or deep or well-directed.

All of these films share one commonality, that being a kind of emotional center that humanizes a cast of monsters.

While it is a pity that the story wasn't told with more visual finesse, this is trivial compared to our real-world problems. It takes a good movie to put that into perspective.
