Adaptations usually need a goal in mind to work. The goal of The Hours? To be a music video for depression. The goal of Bridget Jones's Diary? To not be its sequel. Most of the time, though, adaptations have no goal in mind other than tempting book-lovers to part with their money.
On that note, filmjerk.com, having read David Hare's script for The Corrections, implores you to LoJack your wallet:
A script has never gotten me so down in my life. Maybe it was the intense, four-day experience I had with the novel. Maybe it's that a lot of The Corrections cuts close to the bone for me. But mostly it was a feeling of despair. Here's this terrific piece of literature and the man adapting it has no idea who these people are or what the story symbolizes. Anyone, even a first-time writer, could have delivered a script as good or better than this one. It feels like such a waste. It feels like Hare wrote this with the thought in his mind that the script would never get made.
If only it wouldn't. (But, since it will, here's hoping that CGI makes a convincing talking shit.)
