There is a point in the Black Christmas remake, right near the beginning, where one of the characters suggests that they call the police. This is in response to a very disturbing call that purports to be from a spree killer incarcerated for murdering his family. The female characters are members of a sorority, staying in the spree killer's childhood home.
They don't call the police, opting instead to talk about opening gifts.
That tells you everything you need to know.
This is a stupid movie, even for a slasher film. Rent the original.
I'm not sure what the deal is with remaking decent horror/slasher films. There are plenty of stinkers from which to choose.
I'm of the opinion that you should only attempt a remake if you can do it better, or at least do it different enough to feel original.
I feel the same way about cover songs.
