Yeah, I understand that argument. I put Monster's Inc in a similar category as TRON going to MK. I don't think long term it hurts the park, but it wasn't what the park needed. It's another D/E ticket that will likely have insufficient capacity relative to demand.
Personally, I'd like to see the following "small" things addressed in this park:
- Spinner or other flat ride added to Toy Story Land beyond the restaurant. The obvious choice would be a slight retheme of TriceraTop Spin to Trixie's TriceraTop Spin. I'd also accept a carousel in that area.
- New stage show to replace Beauty and the Beast
- New video in the Mickey Shorts Theater. Longer term I'd accept a replacement of the entire Frozen/Mickey Shorts complex with a ride.
Longer term, it's probably logical that any Animation Courtyard re-theme rolls in RNRC. The Mermaid show and Villains show are probably being run as ways to extend the useful life of that area and delay whatever is ultimately planned. If either of those shows are popular it would undoubtedly delay those plans even more.
Of course, the elephant in the room is that the park desperately needs a boat ride of some sort.
