Yep.
I'm getting old and cynical. It takes a lot to impress me. Batman Begins impressed me, for instance, in that it not only managed to be good, but actually overwrote the sectors in my brain devoted to "Forever" and "& Robin".
But seriously, H2G2 was rubbish. Every character that was in the film was eclipsed by their TV series counterpart. David Dixon ("You're all a bunch of bloody loonies", "Why yes! That was it.") makes Mos Def look like a pedestrian, jobbing actor who can't even decide what his name is, Mark Wing-Davey oozed ultra-cool compared to slightly-confused Sam Rockwell (and what is Zaphod Beeblebrox if not ultra-cool?), Stephen Fry acquitted himself but was always up against the memory, and clipped tones, of Peter Jones, Simon Jones ("What?") makes a mockery of Martin Freeman - even Bill Nighy's much-vaunted Slartibartfast is nothing compared to Richard Vernon.
In fact even down to Mr. Prosser - whose part is so badly cut - every TV actor eclipses every film actor. Only ONE even matches the original. Bill Bailey as the Whale - and he could have done better with the FULL monologue. Okay, two - maybe Alan Rickman too.
The film was so bad I can't even remember what Humma Kavula did, and I'm lost as to what Zooey Deschanel (Trillian) even looked like.
And Helen Mirren as Deep Thought! Helen Mirren!
The fundamental problem was that the story is big. Really big. You just won't believe how vastly, hugely mind-bogglingly big it is. You may think it's a long way down the road to the chemist, but that's just peanuts to the story.
The TV series tried to squeeze it into 3 hours. It was tough but they preserved the majority of the good lines and humour.
The film tried to cut it down to just 109 minutes. And ADD more stuff. And they didn't preserve the majority of the good lines and humour. Had Douglas not died we'd have seen a more cohesive script, though the film wouldn't be out until 2012 ("I love deadlines. I like the sound they make when they go rushing past."), but it still would have been Hollywoodised - a massive story crammed into an hour and a half.
