I used to be the type of person who thought 'the Saw films? Ugh, torture porn! What kind of sickos would actually want to watch this filth?' Of course, like so many others, I was judging the films before I'd even seen them. However, all that changed when I watched the original Saw at a friend's sleepover. I found it to be an excellent film which had a strong plot and an equally strong cast. It was not, as I had previously guessed, a story based around torture but the traps were expertly woven into the plot. Of course, this set me off to watch the rest of the series and I have not yet been disappointed. One of the truly great things about this franchise is that all of the films inter-link. As such, there is a real reward for fans of the films. Having said this, I would say to anyone reading this that you will most appreciate this film if you have previously seen Saws 1-3. If you haven't, it is an understatement to say you won't have a clue what's going on at some points! For me, Saw 4 is my favourie in the franchise. For one thing, it is the most stylishly shot film in the series - the whole thing looks darn good. This is especially true of the end of the film - it really is the most epic moment in any if the series. The twist is one of the absolute best as well. In conclusion, you really don't have to be a fan of horror to watch the Saw films. I'm not, and I have the whole collection. They are plot-driven, well-made and worthwile films. And in my opinion, Saw 4 is the best of the bunch!
