This is completely pointless movie, one of those where you watch it to see what happens and then it just ends suddenly and you think WTF? Normally in slasher movies like this you'd think the weakest points are the plot and the acting. Surprisingly, there was nothing wrong with the acting. The main cast did what they were meant to but the ultra poor script didn't have any proper development for each character so there was nothing much to feel for any of them. Even the premise of the story didn't make sense. A huge guy with a bandaged face sends out chain letter e-mails to people with the threat of death of they don't play the game. What the game is...no one knows because all the letter says is that if you don't play you die. There's no mention if you delete the e-mail you die or if you don't forward the message you die. This movie is that lame that a few simple rules aren't even scripted in.
Some of the deaths are truly gory, even by Saw standards. But in the grand scheme of things they are entirely pointless. Even the Saw scenes had some intelligence to the deaths- you're a bad person but you get a chance at redemption but not until you go through a trial by fire and lots of pain. The deaths in Chain Letter are just gore and pain. This makes watching any Paris Hilton movie fun and educational.
Deon Taylor should be made to undergo one of the death scenes in his movie- either that or threaten him with a scene if he doesn't stop writing and directing such rubbish.
Recommendation: only if you like to pull out your fingernails with a tweezer dipped in acid.
