Fantastic and imaginative exploration of how a young person might deal with grief. Brilliantly told by Patrick Ness and superbly realised by J.A. Bayona, this is one story that balances drama and CGI with aplomb. Incredibly moving, deftly handled and one of my favourite films of last year. Liam Neeson's gravelly voice is brilliantly put to use as the tree. It's wonderful, please watch it!
