The problem isn't just having "too much" or "too little" of something. Every theme or amusement park has too much or too little of something.
The problem is that Universal finds a ride type they like, and then builds it repetitively with little variation in between.
They redid Spiderman in 2012, and copied the ride system for Transformers in 2013.
The built Kong in 2016, and copied the ride system for F&F in 2018.
Before and between those, they opened two other screenz simulators - Minions and Fallon.
More recently in IOA, they rebuilt a big outdoor launch coaster in Hulk, and then started on two more large outdoor launch coasters: Hagrid's and Velocicoaster.
Where are the big physical dark rides? The boat/water rides? The flat rides?
They just don't need another big launched coaster right now.
