First things first - the book is great. Emotional, exciting, character driven and honestly relevant to anyone who has had an older relative with any kind of dementia. Now for this adaptation. It's awful. I could honestly talk al day about what's wrong but I don't need to. The main issue ... and it's a big one is - Grandpa. My god he is portrayed as a boring slow and incapable pensioner that couldn't find his way into bed never mind be the hero of the story. We thought of him as a hero. An old school fighter ace who sounds just like you'd expect - big tash stiff upper lip type that loves wollaping jerries - in this adaptation he's practically asleep. This fact alone makes this adaption unpalatable. Basically the hero of the story is almost in a coma. It ruins the entire program and makes it ... well like grandpa ... boring and unbelievable
