"There's always one! I suppose they get some sort of perverted pleasure from breaking in on other people's conversations in which they obviously have no interest just to tell them how superior their lack of taste is."

Yeah, partly, I suppose. But I'm always pissed off at the way that the SF genre, which was once original and innovative, has been appropriated by know-nothing idiots who present their cretinous creations, on TV and on film, as the 'real thing' - when they are, in fact, ludicrous, perverted travesties! I feel no shame whatsoever about pointing that out!
