Chain Letter is only scary for people who are taken aback or feel concerned whenever they receive messages through email or facebook that say "Send this to 10 other people or else!" Some people actually feel uncomfortable and fear the consequences unless they send it to 10 other people. I know crazy right! That's basically what a chain letter is, and what makes up the plotline to this "horror".
Now I'm willing to give this movie a little bit of a break because despite the bottom of the barrel choice for a plot that's way too typical of the modern age we live in grasping for anything to wrap a movie around, there actually ARE a few decent moments in Chain Letter. I enjoy the death of a person chained to the back of two cars, so when the cars drive down the road the person chained gets smacked around experiencing bumps and bruises in graphic fashion. This is especially thrilling when the lady in the right car looks in the mirror while stopping at a red light and realizes there's a body attached to the back of her car but... she can't warn the guy in the other car in time as he speeds off so yeah, that poor body, haha. For additional effect maybe they should have filmed these particular scenes somewhere in Pennsylvania, har har! In case you don't know, PA has some extremely bumpy roads. Would have been ideal I tell ya!
Anyway the other deaths involving a girl rather realistically dying after a spear goes through her head is pretty cool, as is the one where the teenage boy gets his face ripped apart by a chain tightening across his face. I can't even imagine what it would feel like to have a chain smash my face in such a way. Maybe these deaths aren't original at all but I've never seen them before in other films so for now I'll consider them nice moments of creativity. How about that guys head who gets squashed like a supersized bug while looking at his car motor, haha. Blood just dunks out of his head like a giant bin of red pudding.
Otherwise the storyline is just really bad. The acting is below average (the brother and sister arguing over a computer with childish insults is plain writing) and the cop detective going around figuring out clues wasn't a good actor either and seemed somewhat arrogant and inappropriate for his role. Lousy acting all around by everybody. Only the deaths can save this one. It's passable only for the deaths, but please, if you know what a chain letter is and have received them online, you'll probably end up mocking or flat out disliking the choice to base an entire script around the subject. It's just not worthy enough for a horror film.
