It's hard to see any effort in the film. There's no comedy to speak of, no real drama and, worst of all.

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

The movie's not perfect, but it sticks the landing of its message. It was engaging - thrilling at times - and I personally thought it was a great time.

There's a more than satisfactory amount of boom-boom in the movie's trim running time.
