Keeping your kid from watching the PT? That's a little over the top. This is a different generation, and they have every right to enjoy things that we don't enjoy. In fact, it doesn't bother me at all if the younger generation doesn't like the original SW and prefers the PT. They also don't like the Beatles, Miles Davis, and a host of other things that earlier generations consider great. However, they should learn to respect that which came before, because the things they love will become passe too.
That said, I think that eventually anyone with an IQ over 90 will realize, on their own or with a modicum of education, that the PT sucks and the OT rocks.
