... or is it just pure snobbery on my part ...? 
I helped out at DD's school for World Book Week today, taking orders from 4 to 6 year olds. I took twenty-five orders. There were roughly 300 different books they could have chosen from, but every single order was for Tangled, Toy Story, Star Wars, and another one which I can't remember but the point is, they were all film tie-ins. Not books written as books, but cash-ins on films. AIBU to emit a large sigh ...?
