I think the current trend to remake movies is a clear sign that there is a lack of new, fresh ideas that would make us, the punters, leap from our couches and go through the wonderous joy that is visiting your local multiplex.
Remakes ae a safe as houses bet. You've got the background work done, the public are familiar with the original film. All you got to do is throw a few million quid atit, slap in a car chase or some other rubbish, and hey presto, decent opening week at the box office, good run on DVD and then of to telly with you.
A good example of getting it right, in my opinion, is the recent remake of Dawn Of The Dead, a remake I was pretty sure would both suck AND blow. However, it was pretty darn good. They embellished the idea of a terrifying day when all things bad began to take over, chaos reigned and we mortals became a moving buffet. The characters managed to be a little more rounded than in Romero's original, and the gore more than stood up to the 1979 version.
An example of what NOT to do with a remake was the remake of Get Carter. Pure film making by committee. Swapping the central characters around, making Carter not the cool violence machine that Caine played him as, but a lumbering oaf as Stallone played him.
