(In case you're visiting only to vote, please remember that we're looking only for films that have been released in the past 20 years. Thanks!)On Wednesday

, I polled readers on the best and worst film adaptations of children's books and found some surprises, some no-brainers, and some upsets. The results will be posted on Monday.Sure, we focus mainly on children's books here on the blog, but that does not mean we at Upstart Crow ignore adult titles completely (just ask the wonderful Danielle Chiotti, who is our resident specialist in adult titles). Given our love of all things literary, we'd be remiss not to discuss the best and worst film adaptations of adult novels.Because the adaptations of novels go back to the very beginnings of cinema with classics like All Quiet on the Western Front, The Grapes of Wrath, and Gone with the Wind, I've decided to limit choices for best and worst adult film adaptations to movies made in the last 20 years because, if the children's choices are an indication, the nominations will be all over the place. And besides, The Godfather would have been tough to beat for the best, amIright?So please follow the same format as before in voting for your most/least favorites. List your selections like so: "Best: How the Grinch Stole Christmas (the original) Worst: Twilight" Please limit your choices to best and worth to only one in this format to make it easier for tallying purposes. If you'd like to list runners-up or comments afterward, feel free.The results from comments and from my concurrent poll on Twitter (follow hashtag #books2film) will be posted next Monday. Let the votes begin!
