I know most would classify TDL's Pooh as an E but I probably wouldn't(even though it most definitely is a can't miss attraction at TDR)simply because it's not as substantial as say Everest, Mansions, Space Mountains, Test Tracks, ToT's, IJ's ect.----- it just doesn't have a large venue nor does it use grand sets(although it certainly uses high quality sets); even its facade and queue are modest ...... and I'd say that Roger Rabbit is closer to an E event(even though I call it a D) because of its facade, eleborate queue and many show scenes with realized AA's ///Another thing about an E is that if done right, they become instant classics/// I agree. But I'm careful not to classify something an E just because it has a huge and instant following like Pooh and Soarin'. And the reverse holds true with me--- I would very much call EPCOT's Universe of Energy a bonafide E even though it doesn't seem to attract the masses or have a big following..... that attraction uses very large scale sets and has an impressive duration.
