My imagination is a pretty powerful thing. It can take branches outside my window and turn them into murderous fingertips in about five seconds. Which is why I generally try to cut film adaptations some slack. If they're competing with something I've already read, they're in for some stiff competition.

That doesn't mean I've never left a movie theatre wishing I could gouge my eyes out and erase the last two hours from my memory. In fact, if you asked me to name good and bad film adaptations, I can rattle off a long list of offenders (Everything is Illuminated and The Handmaid's Tale are the first to come to mind). But if you ask me to name some of the winners, I have to think a little bit.

So when we asked for your best and worst lists, I expected the bad reviews to come rushing in like a raging river. But surprise! We've actually received more comments on good films than bad ones.

That doesn't mean you've let the folks in Hollywood completely off the hook, though. Here are some of the offenders so far:

Simon Birch: Based on John Irving's novel A Prayer for Owen Meany, this one is a common offender due to the fact that it is so different from the book. It doesn't even have the same ending! John Irving himself requested that the film have a different name so that people who read the book wouldn't be disappointed. We got this suggestion from Corey Redekop, who thinks it "massacres any goodwill" towards the novel

War of the Worlds: Steven Spielberg's adaptation of the science fiction classic by H. G. Wells got mostly positive reviews after its 2005 release. Not from commenter b_dumoulin, though, who had "such high expectations that (Spielberg) would follow the original story by setting it in England in the period around WWI, but instead he turned it into an action flick for Tom Cruise."

The Shipping News: The 2001 film of E. Annie Proulx's award-winning novel has come under fire from commenter Spinnaker 709 and our own Kimberly Walsh. Truly, its crime is the worst a film adaptation can possibly commit — getting our hopes up and then letting them down. According to Spinnaker 709 "I loved this book, and as a Newfoundlander I was looking forward to the movie, especially with the great cast, but it was just a horrible, thrown-together movie that really disappointed."

So let's hear it. We've all seen the film factory take a book we love and turn it into some twisted, shallow, misinterpreted version of itself on the big screen. Tell us which film adaptations made you want to throw your popcorn at the screen and walk out in frustration. We can handle it.
