It's not great by any means, but it's a pretty good movie that didn't leave me filled with regret for investing time in it.

While it doesn't offer any answers, it both thrills and makes you think.

The film may be flawed, but its message is not.

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.
