I was around for SW in '77 and I can say I'm definitely nostalgic when it comes to the PT. I have qualms about all 6 movies, but I don't let it blemish the enjoyment of watching any of the films. And when I say qualms, I mean the OOT and the SE's, as well as the PT.
As an adult it's easy to find fault in what essentially should be a children's movie.
