Things I only made myself read because there was a big-budget movie coming out
Lord of the Rings (which was worth it; if skip of the poetry and fast-forward to Rivendell)
Watchmen (and I can't see any way a movie I'd enjoy would come out of, and so won't be watching it unless it shows up on a $.01 pay-per-view day or something)
I will continue to insist that book 7 of The Wheel of Time was, in fact, one of the best in the series... and have no regrets on giving up on A Song and Ice and Fire after book 2.
