The TV version of Chris Morris’ Radio 1 series Blue Jam (plus the late-night counterpart, Jaaaaam, also included here) pushed beyond the edges of comedy with an almost sadistic determination into a blurry miasma of appalling, nightmare scenarios, Kafkaesque horror and bitter, acidic satire, to the bleak accompaniment of a dark ambient soundtrack. The heaviest ‘light entertainment’ ever attempted, Jam didn’t so much make you laugh as fill you with a rapt, faintly nauseous feeling of unease.
