Just want to point out a show doesn't exactly need to be action packed to bring in crowds every night (Fantasmic for example)...but if Universal doesn't make it action packed, they are going to need to make it emotional and with actual stakes.
A lot of issues with the musicals and non action show Universal did like Creature of the Black Lagoon the musical at USH (the music also wasn't that good or catchy imho), Sinbad at IOA, etc were they were way too cheesy and juvenile. People still like juvenile things in general but they want things to be a little bit smarter.
The parks should really leverage other divisions of NBCUniversal for help in creating their shows. It's not like NBCUniversal and Dreamworks don't have their own stage production areas (Universal Theatrical Group). IF not UC show then get Cinco Paul (Schmigadoon), Garth Jennings (SING), and Stephen Schwartz (Wicked and the Prince of Egypt) to work on something original for the parks since Universal has excellent relations with all three.
Otherwise Universal has Wicked, Billy Elliot, Cry Baby, Mean Girls, Shrek The Musical, Bring it on the musical, Back to the Future The musical, Prince of Egypt the musical, and Catch me if you can the musical.
The reason why Wicked didn't work well at USJ is the completely rearranged the show to have it start in the Emerald City talking to the Wizard than going back to Shiz University than ends up hitting defying gravity and ending with For Good. The show made no sense and was just essentially lets have people sing popular songs from Wicked and try to make a storyline but no really. Lets not try this again for a 30 minute show.
