I tripped over a movie that I hadn't noticed before: Earwig and the Witch, and the only reason I watched it was because it's apparently a Ghibli film. Looking at it, you wouldn't be able to tell, it doesn't have the typical, handcrafted style of a Ghibli Film; but apparently it was made by Hayao Miyazaki's son: Goro Miyazaki.
It uses a CG style instead of a 2D Animated style, which I was willing to give a go, if only because I feel that the new Miyazaki obviously wants to set himself apart from his father.
Ultimately, I'd have to say that the movie just wasn't that good. I have to make a concerted effort to not look at their faces as the characters are talking, as the mouths don't match the words being spoken at all, and it's really freaky. A lot of the CG just doesn't lend itself very will to allowing the characters to express themselves. The movie also lacks the kind of grandiose and awesome worldbuilding that you might expect out of a Ghibli movie, with the majority of the movie taking place indoors.
The writing is very unnoteworthy, and honestly the story just doesn't go anywhere. After you're about 90 minutes in, where it feels like the movie might be picking up steam, it just ends unceremoniously. The characters don't have the kind of development that you'd expect out of Ghibli movie, and there just isn't any real climax, so it felt very unsatisfying at the end.
Then to rub it in, the credits sequence has what looks like concept art of the characters in the more traditional Ghibli-style, and it just looks quite a lot more enjoyable than what we got.
Better luck next time Goro.
