The movie was terrible. It was 80 minutes of humans acting like morons and screaming a lot, interspersed with about 10 minutes of truly badass Alien on Predator action.

The effects were good, the backstory was nice and the actual Alien/Predator carnage was honestly pretty damned sweet. Too bad that the other 90% of the movie focused on the "sassy black chick" bonding with a Predator while her friends were being killed by Face-Huggers.
