I think the magnificent 7 is one of the few remakes that is a classic. The remake of Cape Fear was good as well, if not quite the original (I saw the remake first but still prefer the original).
There's no point in remaking classics generally though (see the Psycho remake for that one. tried watching it once, gave up and put on the original after 20 minutes) as you can only screw them up. What we need are remakes of bad films that had a good idea behind them. there must be hundreds of those.
