Pointless I suppose if you've never read any of the Hitchhiker's Guide series, you might find this movie to be 'an entertaining interstellar romp" or some such nonsense. For the rest of us, save your time and money. I was very disappointed.
This film resembled the original novel in that it includes the same characters, some settings, and a basic plot line. From there it deviates in to stupidity. I don't fault the majority of the cast cast. I lay blame squarely on the inept directing of Garth Jennings, and the embarrassing overacting of Sam Rockwell. As a director with no feature film experience, he was way out of his league. And Mr. Rockwell is not the comic 'second coming'.
The entire storyline has been butchered. Changed from a fish out water tale to one of lost love. The credits list Douglas Adams as the screenwriter, but I find it hard to believe that he would have allowed some of the inconsistencies that appear in this film, or sign off on the confusion of the project.
In the novel, Arthur Dent is ripped from his world into the wild and crazy outer space world of Ford Prefect. Prefect is portrayed as, well, I don't know what they were trying to do. In the novel, Prefect is a man seeking pleasure wherever it is, and avoiding work whenever possible. Rockwell's Zaphod is a jerk. In the novel, he is a wild crazy playboy adventurer. The entire storyline involving Trillian was skipped, and her character seems bored to tears. Zooey Deschanel was wasted here.
I must say that I was pleased with Mos Def's performance. He did well with what he was given. You got the sense that his character was truly comfortable in the crazy world he lived in. Sam Rockwell, on the other hand, trampled his character. You have to wonder if these actors read the book at any point in the conception process. Rockwell turns a blissfully unaware, super rich playboy of a character into a mean-spirited jerk of a character who merely distracts from each scene he is in. Overacting does not substitute for character development. The twin heads SFX became tiresome after it's second appearance, ruining the duality of the Zaphod character.
It's not that HHGTTG isn't nice to look at. It is. The colors are vivid, and the sets are marvelous. I'd expect nothing less from a director with music video experience. But the glitz attempts to hide the lack of substance that permeates this bore.
For sure, it'd be easy to pick apart the technical differences like a Star Trek geek comparing the movies to the various series, but that's not the point. The fundamental character of the wonderful novel has been changed. The tone of the film is overwhelmingly negative, whereas the books are relatively positive works. They're fun. This was not. Not recommended.
