100 minutes even, but I still watched it at 1.5-2x not because it was badly made, but because the subject matter is so depressing -- how a bullied 12-year-old boy copes (fantasies, escapism) while his mother dies of cancer -- that I couldn't possibly sit through it at normal speed, and have no idea why anyone would torture themselves this way -- no child should ever see this!

Sigourney Weaver as grandma with fake British accent. Video game-like storytelling sequences mixed with watercolors, and a fiery ent with a nightly parable to hit you over the head with....

Full red, avoid.
