The characters had their own nifty stories and they interwove creatively. The crazy goat is loads of fun. I think the songs were well-done. The animation isn't impressive but I still like the large scale of the woods and its atmosphere. The twist is rather silly but then again what isn't here?
When I first saw this I was excited that they'd kept it open for a sequel. However the sequel, which came out much later than expected, is apparently bad and I don't plan to view it. Still, I recommend this first film to anyone who enjoys an hour and a half of easily-accessible humor.
All of that doesn't detract from its positive qualities. It has a great all-star cast who all give great performances, bringing the characters to life. Not a single actor doesn't do a fantastic job. The script is weighed down with some outlying corny lines and awkward phrasing, but it all sounds fine coming from the actors. The little subplots that they each have are interesting and don't get old despite repeating a lot of events. That can easily keep me entertained. It all leads up to an unsatisfying finale that ends with a blatant sequel-bait, but I digress. I still find the whole movie to be a lot of fun.
