I've always loved this classic, and now my daughter adores it too, and I get to see the film from a parents' perspective. It's just so beautiful, Disney really did an incredible job blending 3 animated shorts of Winnie the Pooh and turning it into a seamless film. The tunes in it are cute and catchy, such as 'I'm just a little black rain cloud', and it works so much better with kids than the more recent over-the-top Disney musical pieces found in Alladin or Lion King. Seriously, who the heck thinks kids want a full blown orchaestra piece? Just give them short and sweet tunes and they're in heaven.
The more recent Winnie the Pooh exploits from Disney, with Heffalump and other atrocities, and the mass marketing found everywhere, I can't stand, but this original classic is a true gem.
