My kids love this show. It's cute, and fun to watch! I love the songs and it's also entertaining enough that I'm not bored watching it with them. It's also nostalgic for me, the animation reminds me of the Powerpuff girls, or Fairly Odd Parents. Brightly coloured and moves at a good clip. I like how the episodes are such a short length too, it's good to put on when the kids want to watch something but don't want them in front of the TV for too long.
Not sure why there are so many negative reviews, its thoroughly enjoyable and entertaining. Has positive messages too.
The voice actors do a great job too, Lucy voice is adorable, and I love Captain Snappy.
