A cut isn't happening here.
Spectromagic wasn't happening on weekdays during the offseason.
Fantasy in the Sky wasn't happening on weekdays during the offseason.
Spectromagic did play everyday during the 25th anniversary - when the celebration ended, so did the daily showings in the offseason. Was that a cut - not really since it only shown daily during the 25th anniversary and had been advertised as such. The Big Mac going back to $2.50 following a sale price of $1.00 isn't a price increase. It just was the end of the sale.
If Spectro and Fantasy were cut on Saturdays - then yes, that would be a cut. I don't expect that to happen. So, this is an addition. Maybe you wish they would add something else instead (more Spectro, more Fantasy) but nonetheless, it is an addition.
Every addition doesn't satisfy everyone - bet that there is a lot of people that could care less that MGM added Tower of Terror because they will never ride it. That doesn't mean it shouldn't have been added.
Some people will love one more opportunity to see the characters - and to say goodbye to them at the end of the day. Since it isn't replacing Spectro or Fantasy, it's something extra.
