I'm not opposed to an Indy land but wouldn't be thrilled if it took over the Theater of the Stars area. RnR already sticks out like a sore thumb next to the old Hollywood vibe of ToT and Sunset Boulevard. I would love to just see the theater plussed and BatB replaced. And I don't say that lightly, because BatB is my favorite Disney movie...but the story is so condensed and the wardrobe and set design so underwhelming that watching is a disappointment.
TBH, I think the Frozen Sing-Along was a brilliant move by Disney, because it takes inspiration from Frozen, but stands as its own show. I've seen it several times and laughed out loud at each performance. The comedy is good, the sing-alongs are enjoyable, and because the storyline is so simple (Anna telling the story of her sister through songs while they wait for Elsa to join them), the show never feels rushed.
I'm all for full-length "Broadway-quality" shows like Aladdin and Frozen over at the Hyperion. But I think 15-30 minute, lower budget movie retellings just don't work. I say stick an elaborate, movie-based show in the new MK theater, and replace the shows at DHS with self-contained stories that are inspired by Disney movies but don't attempt to rehash the whole movie in 1/4 of the time. Like, instead of trying to tell the story of Tangled from beginning to end in a 25-minute show, give Rapunzel, Flynn and co. a brand new conflict w/ a plot that makes sense in this kind of timeframe.
