Question #17: Book turned movie and completely desecrated.
It only makes sense to get the opposite of yesterday's question. I tend to avoid movies based on books until I can read a few reviews and I'm very good at completely blocking crap films from my memory so I was actually reduced to trolling the internet to job my memory for a film that could fit in here. Thank you internets for reminding me of the abomination which was the Jim Carrey vehicle How the Grinch Stole Christmas. There was already a perfectly delightful cartoon adaptation which everyone has watched at some point. There was no reason for this version. No wonder I've blocked it from my memory.
Now, if you'll excuse me, I have to go to YouTube and find the cartoon version so I can once again remove the live-action version from my memory.
Addendum: I just realised that I am posting this exactly three months before Christmas.
