I agree, the original stories are something very special. The Disney movies are very hit or miss - the ones which stick close to the stories are generally good renderings of the original tone. The 'cash grab' holiday themed ones are generally awful.
There are moments in those stories that made my kids and I laugh out loud - Eeyore is such a funny character. Him drifting down the river in the "Pooh sticks" story is a mental image that still brings a smile to my face.
I've always loved the way that the other animals treat Eeyor.
