I have to admit that I thought this move was an average thriller until the last five minutes, but those 5 minutes make you stop and say 'wow' all through the credits and you'll want to tell everyone how it ends even if most of friends are guaranteed to of seen it beforehand. The saw series will remain thriller/horror classics and your really missing out on a piece of history by not jumping on board.
Bad acting may be seen through out the movie, but its not what your thinking of by the end, the killer is great and the ending is explained so well with so few words? (You could guess I'm trying not to give it away.)
Saw makes you think about how much you value your own, because the victims in this movie really didn't value their own lives until they knew how long they had left. So if you don't mind watching a little bit of blood and watching games you know are one sided I would say grab some mates and start at the beginning of this soon to be classic series.
7.5/10
