I didn't expect much based on the cover and the topic, but this was a very well made movie with quite a bit of emotional depth. I thoroughly enjoyed it and was rooting for the main characters. There is a good deal of fighting but it is secondary to the story of the brothers, all in all, I definitely recommend this.
A modern classic, this epic sci-fi action flick has every element needed to make a blockbuster. I remember when this movie came out it blew my mind, nowadays you can't consider it incredibly deep but it maintains being a rock solid rewatchable extravaganza if you're into that sorta thing.
