Don't you think they would have more impact if they were one off's. Thinking, Misery, The Shining, Texas Chainsaw(not the re-make), to me the point of a horror movie is to chill you to the bone, that , these people could /are out there. The concept behind alot of great horror movies, like Elm Street, Hallow'een, Saw, and more recently Hostel, are chiling, but they lose their impact in the sequels, obvioulsly hollywood works on ticket receipts, but must this be at the expense of the movie goer. The best horror i have seen in recent years was Cabin Fever, it had the gore, the humour and the story.
There is no shortage of horror in the world today, why do film makers insist on re-making old films, fair enough giving credit to your influences, but surley they have more imaginative ways to show their respect?
