I've flipped that switch for book adaptations.

I let go of fanboying on what Hollywood "did to" the story and instead just decided to be thankful something I love was given a new medium / audience / interpretation... and voila! now I have two things to love.

It's still fun to point out where things could've been done differently, but instead of actually disliking the film(s) because of those things, it's just another mechanism that lets me talk to my friends about something. Much more fun than riding home in silence in any case. ;)
