Better than expected but the bar was seriously low. I think if this was a completely stand alone thing without prequel baggage it would have been a reasonable little sci-fi thriller, but it isn't.
It's impossible not to compare it to the original, which had in its favour a cast of memorable and quotable characters, a razor sharp script, a killer Silvestri soundtrack, an incredible ending, and frickin' Arnie. This one has, and why are native American characters always portrayed this way- a dull, overly stoic, personality free cast, a typically dull background score of noise, a plot structure which was essentially a copy of the original, and some god awful CGI. Oh and a completely anticlimactic ending. The Predator himself had more personality in the original than this bunch had in total.
But despite all that it was still entertaining enough and I thought the main actress was pretty great in the fight sequences. Give her a better script and she could be a star.
I'd give this one 6/10. Watchable but nothing special.
