At first I was almost put off watching this lovely animation by some of the poor ratings on here, but I'm so glad I decided to see for myself.
And I must say it was thoroughly enjoyable (despite flagging for a few minutes in the middle). There are plenty of laughs, and it feels delightful everytime the characters break into song.
It's a fun, lighthearted, well animated little flick.
I recommend giving it a go.
