Lewis MacDougall leads a raw and authentic performance, it's nice to see Sigourney Weaver but her accent is a little jarring. The VFX, concept designs, and the authentic photography and locations of England are all pretty solid. There's very little pandering in this movie and very little of the generic American faff that usually accompanies these films. It's quite talky and the four tales conceit doesn't translate easily to the screen, but I can imagine it being a very important film to young children or anyone struggling with this kind of grief, it's a meaty, heartfelt and complex look at this from a child's perspective. Sensitively and artfully told. It's nice to see a picture of the Grandad as Liam Neeson who provides the monsters voice, a small secret to show how grief affects all generations in different but also the same ways.
