I liked the Monster's Inc. ride pretty well, but I'd like to see it better fit into its land's overall thematic scheme - at least on the outside, if not the inside. The ride's only connection to the Hollywood theme is that it takes place in a modern city (other than "it's based on a movie," which would work for almost any new DLR ride these days). However, I don't see any other land in DL or DCA where it would fit any better.
Even though connecting Monsters with Hollywood isn't that hard - for example, entering through the set of a Harryhausen-esque monster movie - it gets a little complicated to do anything like that without distracting from the main story. Also, the queue taking place in the Monstropolis transportation hub presents a problem, since you can't stick a transportation hub building in the middle of a movie backlot the way you can stick a cab company in the middle of Downtown Toontown.
(I also had a joke idea, in which the queue would begin in a boardroom of Hollywood executives whom we would follow back to the monster world .)
The only practical thing I can think of is at least creating a better facade. Something small-world-like, with animated parts, like doors that open and close.
Anyone else have any ideas?
