The soul of old DHS/MGM studios died with GMR. The “heart” of DHS as a park is completely different now. IMO, MGM studios completely enters the realm of the past when twilight zone theme leaves TOT, even if star tours, Indy, and muppets stick around after.
I do hope muppets survives monsters, but a sad sort of realization that I had is that it’s probably in the latter stages of its life regardless. Grand avenue does need a refurb, and there isn’t much space to keep muppets for adding a new attraction, unless they close star tours which I doubt they do until SWGE gets an expansion. add on its age and lack of LL, MV3D is probably eventually on its way out. Hopefully the muppets get a new permanent attraction elsewhere.
