I watched Spin The Bottle because Justin Long and Ali Larter are in it, but let me tell you this... they're seriously slumming it in this one; it's an extremely weak teen horror that is totally unworthy of their talents.
Larter plays Maura Randell, who is recovering in a mental hospital while her son Cole (Tanner Stine) makes himself at home in the house where, decades earlier, his grandmother Lorelai killed several of her friends while playing a game of spin the bottle. Turns out that there was a demon trapped inside the bottle, and playing the game enabled it to possess Lorelai.
This being a wholly unoriginal and extremely predictable piece of crap, it will come as no surprise when Cole and his new high school pals find the bottle and play their own game of spin the bottle - with disastrous results.
The teenage characters are extremely irritating, which wouldn't be a problem if we got to see them all die in very gory fashion, but the film is practically bloodless. There's really bad CGI visual effects, loads of wearisome exposition, lots of kissing (but no gratuitous nudity), and the whole thing is spun out over two excruciatingly dull hours! Justin Long is the best thing about the film, playing the local town sheriff and father to Cole's love interest Kasey (Kaylee Kaneshiro), but he needs to be a bit more choosy about his roles: I'd hate to see him wasted in more worthless garbage like this.
