I was surprised by this movie. It was a great action movie, with a sci fi basis. The best part of it was the creation of the evil character. We could see the premisses of his evilness, but the events that followed sealed the deal. The good guy was a surprise as well. He was an unexpected hero as he had a difficult life as well, but he choose the other path.
Other than that, the performances were really good and the CGI were decent enough, though sometimes they looked awkward. So, 8 out of 10.
