I know that this will not be popular because I know that a lot of people liked Spectromagic, but I did not. It always seemed like an elaborate funeral procession complete with white faced zombies and weird music vibe to the whole parade. The Main Street Electrical Parade with the upbeat baroque style musical accompaniment was far more fun to watch in my opinion. That said, I'm afraid the WDW is no longer the place it was a couple decades ago. Somethings improved, but a whole lot that made Magic Kingdom what it was is gone now.
I'm sure that a lot of what is liked is whatever parade we saw first. I have never been a fan of parades of any type, however, MSEP was something that I enjoyed and could never figure out what the message was with Spectromagic.
