Pet Semetary

I recently saw Pet Semetary on the sci-fi channel. I have been told about it by my friend who read the book by Stephen King. I watched it and really felt sick alot of the way through. Ok so the old man is going on about 'when I was young i buried my dog in the semetary next day it came to my house covered in scratched but instead of being my dog it was evil and sinister' so the younger mans son dies (gets run over) so he mourns and grieves and what does he think, yes bury him in Pet Semetary despite the old mans warning so after that they are terrorised by a young boy and his knife. This film is something to watch but not for people who get sick easily. The acting is in general good and the storyline ok. The gore does go a little far I think. Well what do you think?
