After recently watching Robin Hood it seems like a perfect candidate for a ride. It has the same sort of elements that splash mountain has, plus since its "Robin Hood" people would recognize the name from other movies as well and be interested. The perfect place to put it would be Critter Country, but im not sure how much more room there is. One more that could work is in either Fantasyland or Frontierland, which do have a little room. I also think a few of the
under-celebrated movies should get a chance. Splash Mountain was a fairly unknown cartoon, but makes a dang good ride.
