This sure was...a movie. I don't really know what to say. The story was fine. The animation was fine. The music was was fine. The voice acting varied from decent to awful. The character designs were awful outside of the Gillmans and the mermaid. The dialogue was unbelievably cringe. That's about it. It had one of the most basic plots in Dreamworks library and that's saying a lot. I'm just struggling to find anything relevant to say for a review that's how lackluster this movie was.
I guess the training montage was quite fun and had cool visuals and sound design?
None of the characters really felt very relevant outside of Ruby, her grandmother and the mermaid. Everyone either had light relevance or was just used to fill in gaps and stretch the movie out to an hour and a half. There was an entire subplot with the sea captain guy and the men in the family which ultimately led to nothing and was mildly entertaining until you realise it's completely filler.
That's literally it. Maybe if I was a 10 year old girl then I could have had a better time but that doesn't change the fact that this movie had little to no depth or an interesting message or even plot. I can't believe I'm saying this but I almost fell asleep and that honestly never happens with me. Basically you can tell exactly why this was barely advertised... 4/10 since there were honestly more negatives than positives.
