H2G2 was quite good. I loved Marvin (Big hand to Alan Rickman there) and Martin Freeman did a credible Arthur Dent. Ford and Trillian pissed me off somewhat, but Zaphod Beeblebrox was damn cool. The dolphin song was fantastic, and sung by Neil Hannon of Divine Comedy fame, I loved Deep Thought, the infinite improbability drive and the Heart Of Gold. The mice were funny, and the scenes on Magrathea were incredibly good. The bit with the Sperm Whale was funnier than I've ever seen it before.
The love story between Arthur and Trillian was overplayed. I hate the way that the cinema these days refuses to acnowledge the existance of a movie without a Hollywood ending, and the two main characters getting together. That I think should have been played for laughs, rather than in the serious way it was done.
They could also have cut the section on Vogsphere, and opted for some Restaurant at the End of the Universe instead. The whole Zaphod-being-chased-by-the-vogons-and-some-random-woman plot line made very little sense without Gag Helfrunt, and felt like it was introduced to add another Hollywood esque strand to the plot – the final showdown.
That's not to say that some of the new things weren't good too – I liked the Point of View gun, and the idea-face-hitting-things, and the inclusion of the Jatravartids of Viltvogel VI. And the movie quality SFX were good, but a lot of the humour was surgically removed, and replaced with Hollywood gunk. The opening scenes with Prosser, and the bit in the bar were cut down so much that almost all funny bits were removed. The famous line "I eventually fond the plans in a locked filing cabinet, stuck in a disused lavatory with a sign on the door saying beware of the leopard" was cut, and the humour completely went out of the episode with the "almost, but not entirely unlike tea" with the disposal of the nutrimatic drinks machine, in order to make way for another Arthur/Trillian scene.
Basically, it's a good film. Perhaps I'm too much of a purist, but I feel it lost a lot in the 'movieization' of it. Yes, the SFX are good, but what really kept hitchikers going was Douglas Adams' snappy dialogue, and a lot of that has been pushed aside to make way for cheap tricks, which I don't feel is really in the spirit of things.
The guide itself is suitably retro, but again, I think I prefered the 70's version, personally.
Fans of the TV serise will of course note a few cameos made by Simon Jones (the Magrathean ansaphone message) and the Original Marvin (in a queue on Vogsphere) And I was gratified to notice that I'd actually been to the place where they filmed the Dolphins at the beginning (Lorro Parque, Tenerife, if you're interested) Also, some of the original music was used in the opening sequences.
Anyway, So long, and thanks for all the fish.
