I think the prequels are a small price to pay for all the laughter Frink's edits have brought me. ;)
As for Jedi, like any movie, perceptions and popular opinions can vary over time. None of us are at the same point in our lives as when we first saw it. (Even those who only saw the SE.) The flaws I see in it today will never take away from the memories and joy of seeing it on opening day.
I can only hope I get to experience half that much joy one more time in a few years.
Even a "third rate" Star Wars film is better than a lot of other films that one could name. How many other flicks from 1983 are still being hotly debated today?
