Yes, Shrek: The Musical and Tarzan: The Musical do exist. Trust me, I read the scathing reviews. If Tarzan doesn’t exist, then a bunch of theater critics went on a really bad acid trip in 2006.
Finding Nemo: The Musical was never on Broadway, it’s simply a show at Walt Disney World.
No, I didn’t like Cars, but I loved Ratatouille and WALL-E.
