Luca
Slate sums up Disney-Pixar's Luca as "Call Me By Your Name with mer-boys," which sounds accurate. We would also venture to say that the story, which follows a young boy who transforms into a fish-like creature when not on dry land (and also focuses on his close friendship with a boy he meets while vacationing with his parents on the Italian Riviera), is reminiscent of the Australian TV series H20: Just Add Water. It looks cute!
