I watched the DVD for the film "Saw" a couple of
nights. This was a a violent horror film with a good
deal of torturing on it. On the other hand it was well
made and had some philosophical core idea behind it. Of course
if you find nothing of merit in the writings of Marquis De Sade,
then you will not enjoy the film.
The film was popular enough to have them create a number of sequels.
I think I have seen enough of the jigsaw killer.
