The problem with that guy's review(s) is that I get the impression that he hates the film simply because it's different, and his love of one particular previous incarnation - it sounRAB like the TV series - has skewed his view of the film.
For example, he says he's pissed off that Deep Thought has spent the last umpteen million years watching cartoons. In fact, he is particularly vile about this scene. The problem is, if the cartoon-watching incident was in the original TV series and failed to appear in the film instead of the other way around, I get the impression he would have had a fit. We'd no doubt see "I can't believe they cut the fact that Deep Thought - the second greatest computer in the universe - had chosen to occupy himself watching very basic cartoons while the Earth computed its final answer".
He does raise some very good points - that it doesn't matter what bits were written by Douglas Adams, only whether it seems like it was written by Adams, for example - and like him I am a little disappointed that some witty dialogues were cut out or trimmed, but I do feel that he is being harsh either a) for the sake of being harsh, or b) because he cannot let go of a previous incarnation.
I do look forward to the DVD where, hopefully, many of these trims make their way back into the film.
