Martin Amis writes books about how unlucky, rich middle-class white men are.There are often poor people and women in his books, but they are caricatures and usually "amusingly" grotesque, because he doesn't appear to actually know any poor people or women. I suppose the film is a fair reflection of his work. His old man had a far greater talent that diminished with age and booze and he ended his days as a drunken, right wing, antisemite. Lucky Jim is one of my favourite books, but you can see the roots of his misanthropy which Martin seems to have inherited.
Oh yeah, I read that wiki link you posted. HAHAHAHAHAHA!!!! Gotta love that Rotten Tomatoes "an approval rating of 0% based on 35 reviews".
BBT has landed some pretty odd roles throughout his, ahem, checkered career. There's a lot to choose from, but Lorne Malvo in Fargo the series might be some of his weirdest, so bad it's good acting. I had the distinct impression that he was a) under-rehearsed and b) didn't give a fuck. The series is utterly meh, too much a rote rehash from the original film, so it can at least be said he did inject something different.
Yeah, I quite liked the series, but I know what you mean. It really goes for the "Fargo the Movie" look and feel. BBT was definitely a stand out. The second and third seasons are rather different though. Unusual to have a television show packed with high profile TV and Movie stars across three seasons.
