Yeah, I remember Amityville Horror and it was super scarey along with the first Nightmare on Elm Street. I read the book "IT" prior to seeing the movie and it was one scarey read. I had some wild nightmares while I was reading that book!
The Evil Dead, Evil Dead II and Army of Darkness (A Trilogy) starring Bruce Campbell is both scarey at times and comical as well. It has a cult following. I am waiting for the three to be put together as a dvd box set before I purchase them. I have Bubba Ho Tep which is another tongue in cheek horror/comedy flick that I have not watched yet. It's Elvis vs. the monster, Bubba Ho Tep. I'll keep you posted. If you see it let me know what you think.
As for The Grudge, I will definitely check it out. I have the full home theatre set up with a 40" Widescreen TV so I'll probably wait until it comes out on dvd. We'll see.
