All the characters and floats are from Pixar movies...right?
I enjoyed the DCA version, and I don't think BPB is any more out of place than the Mulan or the Toy Story parades we've had in the past.
Honestly, once Disney started losing interest in the whole "Movie Making" approach to the park and decided to take out backstage pass, closed down our feature animation, put a modern recording studio at the end of a 1940's Hollywood street, and plopped a giant blue hat in the middle of everything to cover up the Chinese Theater, I've found it extremely difficult to find any kind of a coherent theme at the Disney-MGM Studios.
At the moment, A fun new high-energy parade coming to the park is the least of my worries regarding the Disney-MGM Studios.
