My belief is that they should completely gut it anyway for a fresh start. Most of the sets in there are probably rotten anyway.
The Jumanji ride at Garda gives some hope as it doesn't look terrible. Screens and projections can work well in tandem with real elements if used correctly. Can we rely on MMM to do that remains to be seen (especially given the finale of Jumanji).
Though why they'll add lighting is seen as a negative I'll never know. Kind of essential even in a dark ride.
