Skyline (2010)

Jarrod and his girlfriend Elaine visit Terry, an old friend who is rich and famous and living in Los Angeles.  After a night of partying, they wake to find bright lights and an alien invasion taking place.

The group, including Terry's wife and personal assistant, try to figure out how to survive and escape from the city.  The bright lights pull people in and change their molecular structure.  There are giant space ships and alien robots that search for survivors.

At one point they are able to avoid detection by hiding behind a kitchen counter, so apparently the aliens can't detect body heat or motion. This leads me to believe the best bet to remain safe is to hide in a kitchen counter display center.

There's not a whole lot of plot and it's nothing special, but the effects are pretty good and it was better than I expected. If you're up for some mindless entertainment, this is okay.
