Alien Abduction: Incident in Lake County
This movie is done in the style of a teenager taping a family thanksgiving, and is done entirely from the perspective of the camcorder. Tommy McPherson is recording the whole thing...it starts off on a bit of a somber note, as the family dad had passed away some time ago and it's the first Thanksgiving without him. Shortly before dinner is supposed to be served, the power goes out. What could have caused it?
It aired originally on UPN in late 1997, then was rebroadcast in 1998, and was presented as being real. This movie scared the shit out of a lot of people, including me. Watching it again though, it is kinda ridiculous, not to mention the movie has Emmanuelle Chriqui in it, which kinda kills the whole real thing these days. Still, it predates The Blair Witch Project, and has some decent suspense for what it is.
