Like I said, I haven't seen the movie yet, but I'm familiar with the character and have seen all the sketches. I have my own reservations about the movie, but they're not the same as yours. I get annoyed with the probability of most of the dumbasses who watch the movie missing the joke and laughing at the stupid Khazaki instead of the stupid Americans. Like I said, in the television show he never really fucked with blue collar types and if he does in the film, I doubt it's got anything to do with blue collar and everything to do with stupidity.
Like I said, being poor or working class does not make a person an idiot. Stupidity is classless, raceless, sexless etc...
