Pooh is short (3:10 ride time), with a vehicle traveling on a buss bar past simple blacklight scenes. The characters in Pooh have the same basic range of motion as the characters in Pan, Snow White or Alice. I suppose one could take issue with the fact the Pooh beehive vehicle wobbles on a non-traditional motion base throughout the ride, but that's even less a gimmick than the flying boats at Peter Pan. Pooh was also done rather cheaply by Pressler, but that's another story.
Again, I think it comes down to
nomenclature in a unique local culture like Disneyland. No other Disney park has as many dark rides as Disneyland does. So when Anaheim CM's from ride operators like
@raven up to park Vice President's like Jon Storbeck talk about "the dark rides", they are referring to the eight traditional dark rides in Anaheim.
Other rides can certainly have dark ride elements, but are not considered part of the specific list of "dark rides" by Disneyland employees in casual conversation (like
@raven24 here) or public presentations (like Storbeck has done).
Those of us fans who have interacted with those Anaheim CM's, or heard long-time Disneyland employees like VP Jon Storbeck speak at public presentations to the theme park industry at the IAPPA convention, have picked up on their nomenclature.
In places like WDW where
entire parks only have as many rides as a single land in DCA or Disneyland, they seem to apply the traditional term "dark ride" to any and all attractions that are dimly lit. It's a different culture out there.
