You must not see MSEP very often. It goes out without floats on a regular basis because they're old as dirt and falling apart. Maintaining forty year old chicken wire is time consuming.
It's not uncommon for new parades to have issues right off the bat. They'll be rectified, while MSEP will continue to rot at WDW where management sees no problem in serving the highest paying Disney park guests in the world a 43 year old technological relic.
WDW takes such good care of it they can't even be bothered to change the lights on the drum back to "Main Street" from "Disney's". You're right - why would anyone want PTN when they could watch a parade whose newest character debuted in 1977?
You're gonna have a hell of a time convincing people MSEP > PTN considering you haven't even seen it live. There's also threads dedicated to each of these new shows - if you have comments or concerns, you should post in that show's thread instead of starting your own just to bash a show you haven't actually seen.
