Really though, the movie was great. The main guy did a great job, but there could have been more predator action.
In every predator movie ive always wanted the preds to win, always. In this one it was kind of different. I was VERY surprized at the predator killing the other predator, I was shocked he wasnt saved alla AvP BS. That alone made the movie great.
In every predator movie there are always two endings, one for the movie, and one for the series. The movie ending: As stated I love when preds win, but damn, this movie actually made me want the human to win, I really think they did a great job with his character, and wanted him to beat the preds. That really surprized me. The series ending: Could have been better, in past pred movies it usually involves something with the pred history, or some big revelation, this one was only a 'continuation' with showing of a new season starting by showing more parachutes. I would have liked to see something related to 'the big picture' where we saw a glimpse of the selection process, or them getting ready to start a new season on their home planet or something.
Aside from that gripe, my only other was that there wasnt enough pred action (I guess there never really is for my liking), it just seemed short and to the point when they appeared, I would have liked to see more detail about them, their equip, specialities, differences, the fights, etc.
But yeah, id give it a B+ movie wise, A- for predator wise. Youre able to take more away from this movie if you understand the pred universe better, and have read the novels, etc.
