I like many was skeptical of the use of CGI. Let me tell you, it's bad. Looks like a mobile game. And yet that is the least of this movie's problems. There really isn't much of a plot to spoil. It's boring. It goes nowhere. It ends super suddenly as if they just stopped caring. The movie has lots of the Ghibli hallmarks: witches, close up food shots, spunky little girl protagonist, a black cat, and so on, but it feels more like a rip off of a Ghibli movie done by somebody who watched half of Kiki's Delivery Service. Extremely skippable and only memorable for how disappointed you'll feel by the end of it.
