Am I the only one that thinks this movie was stupid?? I'm still not even sure what the whole thing was about. Were those other life forms at night? And at the end when they go home.... why does it seem like the dad doesn't know they're home?? It shows him asleep on the couch and the room is bright and cheery. Then it flashes to them in the room but it no longer shows him and the room is dim and almost cloudy in appearance. Are they dead and visiting the house and think they're alive??? I was soooo confused.
