"Jack and the Cuckoo-Clock Heart" stubbornly remains less than the sum of its parts. But its rich visual imagery suggests the talented artists involved could create something exciting and truly original if they had a better script.

The film is at once enabled and hindered by its utter strangeness, an intrinsic quality surely exacerbated in its English-language release.

Malzieu has created a fully-realized, wildly imaginative storybook world and populated it with eccentric characters.

In spite of problems I still enjoyed watching it.
