For the first time I read a review of the upcoming Hitchhiker's Guide to the Galaxy movie. It doesn't sound too promising:
“The Hitchhiker?s Guide to the Galaxy movie is bad. Really bad. You just won't believe how vastly, staggeringly, jaw-droppingly bad it is. I mean, you might think that The Phantom Menace was a hopelessly misguided attempt to reinvent a much-loved franchise by people who, though well-intentioned, completely failed to understand what made the original popular - but that's just peanuts to the Hitchhiker's movie.”
Ouch. There's also a list of things that do not appear in the movie. [No spoilers in either of these links; a more extensive review with spoilers is available there, however]
I'm still a little bit hopeful for the movie. I don't get my expectations up too high about most movies, and try not to compare books to movies so much. We'll see...
