I've said it once and I'll say it again...
NOTHING is as over-represented as the Little Mermaid in DLR. One of the very few gifts from Pixar Pier is somehow a reduction in Mermaid.
It's literally impossible for them to host a show, parade or otherwise without Ariel. Even the Frozen Girls are absent now from several night offerings.
The thing that's extra baffling to me is Lion King. I think it was definitely overexposed in the 90's... but from a park perspective (worldwide) it's weirdly very limited. The most prominent usage being the stage show in AK/Hong Kong. I personally feel the same for Aladdin from the big four Renaissance films, but I at least understand that was arguably the smallest of the four. Plus technically there is a soft-land for it in Tokyo.
