huh i didn't realise the BBC show was supposed to be good (you're referring to the post-book one, not the pre-book radio show, right?). it always looked kind of silly.
i always liked the books very much, and i thought the movie was, you know, okay. i didn't see how they could translate it at all (sooo much of the goodness of the books is adams' descriptions) so the fact that it didn't suck was a great triumph in my eyes.
