A slow, warm fuzzy, feel good movie. It's never going to be a recommended "this is great you must watch it" movie, but at the same time no-one should walk out asking for 2hrs of their life back. It's essentially a slow paced "coming into your own" movie aimed at the mid to late teens, but enjoyable by the older and younger also. There was one element of the movie I think they could have removed, but that is only my personal opinion. They did a moderate amount of character development for the side chars for the time they had also.My only real complaint is that the 3d-rendering did show through at moments, but overall the animation was, while not great, not bad either.

In general this is an average feel-good family movie.
As I've seen mentioned in another review the actual subject matter (hula dancing) could have been replaced with almost anything else and not changed the story, however the choice does vibe well with the general pace of the movie.

Your mileage may vary, but I do not regret watching this movie, though I probably wouldn't watch it a 2nd time.
I'm rating it 7/10, rounding up from a 6.5/10, because I don't think it deserves to be rounded down.
