Even at a time when new family entertainment will always be gratefully received, it doesn't feel too much to wish for that films for children - sorry, kids - should be built a bit more rigorously than this.

The problem boils down to this question of sincerity. Director Anthony de Emmony does not feel the magic of this story.

Sky Cinema's new family adventure seems built to be consumed and quickly forgotten.

The school holidays are upon us, and I think this is probably the family film most likely to appeal to the whole family, and to find itself rewatched in years to come on the streaming services.
