Sooooooo... Seriously, does the ride even HAVE a story? I see no story.
Pooh tells a story. You're in the Hundred Acre Wood (you enter via storybook). It's a blustery day. You duck through Owl's house. You bounce with Tigger. You go to Pooh's house. He falls asleep. You end up in his dream about Heffalumps and Woozles. He wakes up. It's raining. You're floating in the water. The rain goes away. Pooh eats honey. Not exactly Shakespeare, but it's a coherent story.
Here? It's just... I don't even know. You see Olaf and Sven. Then you see the trolls. Then you see Olaf and Sven with Anna and Kristoff. Then Elsa sings "Let It Go" for no apparent reason. Then Marshmallow. Then everyone waves goodbye. What's even going on? It doesn't feel like you're on an adventure, you're just going around seeing characters from the film.
