This was an OK Pooh film, but I must admit that it is just a tad bit edgier than most Pooh material. I wouldn't say that it's strait up scary, but there is a mildly intense avalanche sequence, and when Tigger goes to search for his family, he gets a bit teary.
This appears to be reincarnating some elements from Pooh's Grand Adventure: The Search for Christopher Robin (which was VERY scary) in terms of the occasional emotional moments, but not too too much. I wouldn't call this the best Pooh film, but I wouldn't call it the worst, either. It has some cute songs and nice, innocent fun, so take your 4 year olds to see it.
