It's more 2.5 stars rather than 3 for me. The storyline and plot is really good. The humour is silly/nonsensical (good for escaping the serious of real life). But there was way too much singing for a 20 min show (minimum 3 songs per episode). I personally didn't like most of the songs and I felt like it didn't really add much to the storyline.
Also, this is supposedly a PG kids show... I beg to differ..
