I saw this movie last Saturday when they showed it randomly on Disney Channel (in Norway) and I was pleasantly surprised. I've seen some trailers and clips from this movie and the animation looked quite good, so although my expectations weren't the highest, I still hoped that 'Tinker Bell were going to be a watchable picture - which it turned out to be.
It's a shame that this film wasn't released on theaters, cause, like Brettster said, it was much better than Disney's recently theatrical releases ('Chicken Little', 'The Wild') and a whole lot better than the previous 'Peter Pan'-cartoon, 'Return to Neverland'.
Anyway, about the movie; It is very sweet in many ways. The mood is reminiscent at the Disney features from the 90's. The animation is absolutely beautiful and detailed and the delightful score (which is sometimes Irish inspired) provides the sweet, enchanting mood of the film. The characters are cute and adorable and the moral is a good one. The movie is a film that families can safely watch together.
And then there's the songs; 'Tinker Bell' doesn't contain many songs, which is good, cause often the songs on Disney's non-theatrical releases are quite mediocre. While the songs on 'Tinker Bell' aren't memorable, they are not disturbing neither and are quite all right.
So do your self a favor and check out 'Tinker Bell'
