I think "cartoonish" nails this perfectly. This feels like a real life version of an 80s "Merlyn & the Dueling Dragons" cartoon that should've aired between He-Man and Thundercats. (Frank Welker surely voiced one of the dragons.) If that appeals to you, you're probably of an age to have appreciated the ride as well.

Walking through last night noticed a lot of one-off costumes I missed before. If you get lucky with timing, it's a lot more than just the mages, which helps it feel less repetitive.
