The second question is how far the BBC wants to go in demonising the working class. Every character is an idiot: even Alan Partridge gets more sympathy. Stoner characters, when they turn up in sit-coms (even in Seinfeld) get a few laughs and minimal screen time. People Do Nothing is a series of stoners shambling about, trying to con the dole and living in a fantasy world in which radio remains relevant.
The plot is three guys, maybe four if you include the one who gets sent to do odd jobs, trying to run a pirate radio station. Had the writers any love of music, it might work: had more than the barest of plots been written, it might have had a satirical point. As it goes, it is half an hour of mockery, that imagines a working class without taste, intelligent or common sense.
A third question is whether caricaturing Bollywood as a twee, trite music is racist or just patronising.
