This is a mediocre teen horror. In comparison to other IMDB's ratings, I believe this should be a 6.1 tops. I'm rating it 1 to offset what I think is an artificially high score. I reactivated my Amazon Prime account just to watch it on Prime Video because of the 7.1 rating on IMDB, and believe me: not worth it! The teens are annoyingly stupid and over-the-top mean. Characters' personalities are inconsistent throughout the story (and I'm not referring to the moments when they are possessed). The decisions they make bear no logic or wits, from trivial decisions (call the SPCA, you fool!) to specific problem solving (blowing out a candle will solve it, really?). The plot is confusing, a bit of a mess. The aesthetics of the hand, with all the graffiti, is silly (a ouija board is much more visually intriguing). I suppose it would be very difficult to make a solid or intelligent horror movie based on such a pedestrian childish premise (teens find an embalmed hand that allows them to contact spirits). I'm the fool here, who believed this could be a 7.1 and spent money on it.
