Evan is the manager at a Costco in a small Ohio town. After the security guard is brutally killed--and skinned--he organizes a neighborhood watch, which includes Bob (Vince Vaughn), Franklin (Jonah Hill) and Jamarcus. At first they keep on running into the local cops, who keep on giving them tickets, but things change when they come across the alien. Yes, aliens have take up residence in their town it's up to this quartet of would-be heroes to stop them from killing more people. The reason they skin their victims is to wear their skin, like a costume. Otherwise, these aliens look like skinny Predators. Their ship had crash landed a few years before and it's taken them this long to make a beacon (from parts scavenged at Costco) to contact their home world. As soon as they do this the invasion will begin. It's an entertaining movie, equal parts action and comedy, with decent special effects. Recommended.
