Aliens show up on Earth, and as usual, they're militant bastards intent on taking over our planet. Aaron Eckhart, Bridget Moynahan, Michelle Rodriguez and Ne-Yo are among the low-key stars of this Marines vs. space aliens action-fest. Think Skyline but ... slightly better. There ain't a lot of subtlety on display here, but it sure delivers on the nonstop action. 116 minutes PG-13.
