Sitting on the couch with my 2 year old son, I've become something of a connoisseur of children's movies at this point. To be blunt, most of the modern "Pooh" films from Disney are pretty much garbage. The Piglet and Roo movies are especially painful, and got tossed out after about 1/2 a viewing each. In both of those, the characters are just being yanked and shoved through the motions by a giant, souless marketing machine that is determined to squeeze yet more cash out of them, even if it has to kill them in the process.
This "Tigger Movie" is different though. Again and again I found that it moved me to tears, and the story, animation and writing all hit home, almost like they were created by people who actually cared deeply about what they were doing. So far, it's the only one of the modern Pooh films I've seen that captures much of the original Disney/A.A. Milne magic. My son loves it too.
