People like to write this one off, and I think that usually comes from resenting its popularity and success.
Showing it to my wife last night, she was wholly captivated. She "never watched past the first tape" 14 years ago, and said quite plainly that she didn't care to invest in watching it "because everyone [the masses] liked it so much". She assumed it couldn't be any good. It was great watching her seeing it for the first time, not really remembering the pieces she had seen.
I've seen it three times, with this being the fourth, and I plan on somehow screening the 3D discs too.
