horror movies

I would have to say Jurrasic Park..I know its more of Action-Adventure based but it really scared me when I was young... I still remember the night when i had a nightmare about a Raptor chasing me inside the house...Had to sleep with my mom that night..She made me feel really safe.Makes you wonder what glorious powers mothers hold. Have you seen Saw4??That's the latest i guess but its more Gore rather than Horror.
