I thought that the one at Magic Mountain was cute, if not a bit outdated. I mean, SpaceJam came out in 1996, right? But the parade seems to have a pretty good crowd every time I'm there.
I'd say if it's themed consistently, or at least seems to have a purpose, then it's great. Sometimes, the parades don't have much to do with anything, so those can kind of stink.
