I love Saw, those movies were good...I have all of them.
I never saw inside but I have seen Hostel and that was too much for me. A friend of mine and I watched it couple years ago and I couldn't stand it...I made it through the end but it has really affected me greatly. It was so bloody and gross, that makes me cringe. I said I would never ever watch that again and true to my word, I never did. She rented Hostel 2 and she wanted me to watch it, I said No f*cking way I would ever watch that...not after first one!!
Normally I'm big fan of Horror movies and most of them doesn't scare me...only two movies that truly scares me are Dog Soldiers and Hostel.
Now...you may think this is funny...but ever since I first watched Dog Soldiers (age 13 or 14 I think) I've been afraid of Werewolves. Now I know in my mind that werewolves doesn't exist but mentally I'm terrified of it and I think it's because of that stupid movie. All other werewolves movies looks so fake but god, this one looks real enough!!
