Right now I am addicted to the Saw films, which is what I received for my birthday. The first three films, extended/unrated and director's cut versions.
I don't know what it is about them, quite frankly. Originally when the first Saw came out I was vaguely fascinated but it didn't capture my interest enough to watch it. Then the franchise grew and grew and suddenly, and very recently, I picked them up and was like "holy shit, these films are fucking awesome." Which in my opinion, they are. There are so many amazing themes that continue from film to film, and it's not like every sequel it's like a different movie altogether (like some film sequels do). Instead, the Saw films are like this continuous huge story. When watching them in chronological order nonstop you get a sense that they aren't just making another film to add to the franchise, they are continuing the story that needs to be told. The more that is unraveled, the more things make sense from previous films.
The films are also so morbidly fascinating and quite unique. Here you have this killer who is teaching his victims morality lessons and how to appreciate their lives by undergoing physical and psychological tests of torture and seeing if they are worthy of surviving by making their own choices deciphering their fates, often which you either die ironically to the sins you've committed or you overcome those obstacles in order to be "reborn". There's something so twisted, demented and disturbing yet very beautiful about that. It makes you appreciate your life and not take anything for granted, and to not treat anyone like shit because you never know. There are some horror films that do this, that make you think, but not as often these days.
And I like films that encourages the audience to think, to really consider the messages being told in the story. It's not all mindless blood and gore, sometimes there is something behind it all.
Other than that, is my line-up of other movies to watch: House of 1,000 Corpses, The Devil's Rejects, A Nightmare on Elm Street (the entire film franchise, which I have the entire DVD box set collection), Tokyo Gore Police, The Ring, Children of the Corn, Ab-Normal Beauty, Urban Legend, Scream, I Know What You Did Last Summer and The Blair Witch Project. And perhaps some others, too. Maybe I'll go horror movie hunting at the rental store or something.
I am truly freaking insane, yes?
