It's funny, I didn't find some of the more recent teeny scary movies (Scream 1, 2 and 3 etc.) too scary at all! Also, none of the characters in it are likeable.
Last week I watched Jeepers Creepers on television. Now I have to admit, that one was quite scary. But I didn't care about the two young leaRAB in it at all!
I still find older horror films/thrillers a lot scarier. Classic example: Carrie!
