Decent movie but could have been better. Special effects are not half bad. The acting wasn't horrible and the creature is just a copy of the Predator (not exact but very similar) A good way to reach out to predator fans by imitating something they love. The added bug aliens are interesting. Even the alien ship looks fairly similar to some of the designs for Predator style ships.
I do wish people wouldn't come down so hard on a movie just because it borrows from other more popular movies. This movie does a good job of making the subjects its own without being too blatant.
