Tbh this can only be a good thing. The theatre isn't equipped for Cinemagique and it would've been a cut down version without many of the effects. It's far better to have a new seasonal show than a rubbish version of an old show.
We don't know what was left or what was removed but is replaceable.
Hope the new show is better than the Marvel one!
