The Boxtrolls

There are cute children's films - like "Frozen, the first movie to which I ever took my granddaughter (then just under three) - and then there is the more challenging kind - like "The Boxtrolls" to which I took her nine months later. We haven't read the source material, the novel "Here Be Monsters!" by Alan Snow, but she knows all about trolls from "Frozen" and other stories and these are very cleverly represented through stop- motion capture by the specialist production company Laika. But it's a little bit scary for young ones, so my granddaughter held on to my hand most of the film and sat on my lap for the final third.

For British adults of a certain age, the characters of the town of Cheesebridge look like people from a Gerald Scarfe cartoon and the subterranean habitat of the boxtrolls themselves is like a cross between the worlds of Heath Robinson and Hieronymus Bosch. The voices are very well-done and for me the best of comes from Ben Kingsley as a hard bad guy and Richard Ayoade as a soft bad guy. Stay for the credits when early on there is a little bit of existential angst on display from two of the stop motion characters.
