Good start, but then it gets ruined

It's the kind of movie you'll want to see a second time with someone who hasn't seen it yet, to remember what it was like to watch it for the first time.

It is neither dumb nor smart enough to be fun, and spends way too much time with its boring human characters.

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.
