This box set is an excellent buy for anyone who has seen and enjoyed the saw films, or like me, had seen the first three, but not the fourth and didn't own any of them.
They are all very well written and produced, each sharing its own twisting plot involving the charactors; which often refers to the previous installments in the sequels. This makes it essential really that you need to see them from the beginning to get the full gist of what's going on and truly get the most out of the storyline.
There's not much to say about the plot without giving too much away. The main character has a terminal illness and decides to spend the rest of his days testing the will of other humans; needless to say this involves a series of disturbing obstacles that his subjects must overcome, often forcing them to part with limbs or mutilate themselves in some way in order to survive/stay alive.
Although some bits are hard to watch, you have to admire the way everything is thought out and how it all comes together. It is not a horror film, but more like a psychological thriller in the way that it makes you think more than it will scare you. Not once is it particularly scary. Disturbing to some maybe, but not scary.
So all in all, I gave it 5 stars, although I would have given them each individually somewhere between 4 and 5; but altogether they are well worth the 5 stars and the money I paid for them.
Buy it if you watched and liked the rather feeble 'Hostel' and you can stand consistant and copious amounts of gore, or if you simply watched one or read about one and fancy seeing them all.
