My review

Rating: 8.3/10

This movie is very entertaining and fun to watch. This movie is very well-made, and the animation is very beautiful. I liked Ruby’s character development evolved throughout the movie. I also liked how the rest of the krakens easily accepted her into their kingdom.

I love this movie, but I don’t understand how this movie wasn’t hyped that much and didn’t have a lot of marketing. I recommend this movie to young adults or people turning into adults. This is a very sweet and heartfelt movie. I love the character Nerissa/Chelsea, I think she has a fantastic character design. This movie has awesome storytelling! DreamWorks never fails to disappoint!

Ruby is a great protagonist, and she is very relatable, she has reasonable motivations to move the plot forward, which is kind of rare to see during a movie. She is a very likeable character.

The plot may not be complex; however, the simple plot makes this movie awesome, and the story is very straightforward during the middle. I liked the sarcastic comments on the announcements before the two girls ditched school to go to the sea.

The plot does follow a cliché of a teenager dealing with not fitting in with others but it’s because she’s a kraken, not because she is insecure about acne or whatever. This film is nice to watch.

This movie is decently good, and I enjoy and highly recommend it. This movie is underrated but it’s not an over-the-top amazing movie.
