I'm saying that if JJ fails to make a good Star Wars movie, and the next guy fails as well, people may come to see the property as "cursed" or simply think that the balance that was struck in the OT is trickier to get right than is assumed. None of us (as far as I am aware of) has ever made a Star Wars movie, so it seems kind of presumptuous to say "I could make a better movie than that!" Maybe, but then again perhaps the prequels could never have been great despite what we imagine, and people may simply accept that after every new movie is a letdown.

Of course Episode 7 will probably be a worthy contender with the OT and in that case I will happily stand corrected.
