There was absolutely no plot, terrible terrible ending and this movie could have been done in probably an hour if there wasn’t those useless parts in the movie. In 3 hours you’d think there would be some character development but no absolutely nothing.
Lots of part of it just leaves you with more questions because some things just super randomly happened.
Honestly the two stars are for the animation and effects.
Spoiler:
Why did that girl just randomly had a seizure when she connected with the tree under water? Why was she different than her siblings and she seemed like she could breathe better under water? But seriously who was her father??
Instead of them showing the useless part of hunting the whales to get the serum, they could have worked on their important characters…
