Well, I think we can all agree that prequels are bad if they're poorly done and creatively challenged, but doesn't that also apply to sequels, remakes, spin-offs, or totally original stories? I mean, "bad westerns are bad" doesn't mean that all westerns are bad. Are we arguing that prequels are more likely to be poorly done than any other kind of movie? 'Cause I've seen some pretty dreadful original movies and TV shows. 
And, as I suggested before, BATES MOTEL is arguably better than either PSYCHO III or Gus Van Sant's misconceived remake of the original PSYCHO.
