'Raw Meat' aka 'Death Line' (1972) - Gary Sherman.

'Raw Meat' aka 'Death Line' remains one of the more eminently rewatchable, blackly sardonic Brit-horror confections, abounding with pathos, quotable badinage, vivid performances, and arguably featuring the most sympathetic cannibal killer since, Roberts Blossom in 'Deranged'. 'Death Line' ALSO works quite splendidly as a grisly satire about the ignominy of travelling on the Northern Line!!!! While many lesser blood-spillers are all glitsy-glossy surface, Gary Sherman's deliberately disgusting 'Death Line' luridly exposes the gruesome lifecycles of degenerated cannibal hominids lurking within the brackish bowels of London's dismally diseased, rat-infested underground!! See feral, monosyllabic, murderously mutated men acting like savage, sewer-dwelling, blood-hungry, human harvesting beasts!!! Sturdier shock-seekers will doubtlessly savour the exquisite torments of witnessing hip young beatniks cruelly cast into a brutally primitive, retrograde ecosystem wherein only the sickest species survive! So, don't be a rube, get yourself a ticket for this terminally thrilling terror tube!!!! This deliciously meaty, mordantly witty vintage treat will derail your expectations, sordidly salivate your gore glands, descending discerning horror fans into a macabre, non-stop nightmare of suffocatingly suspenseful, spleen-spirited, sinisterly subterranean shock!!!  

'Surviving unobserved for generations, shielded by blackened glooms, the wretched, flesh-eating ghouls beneath the busy city streets have been turning unsuspecting commuters into meaty cannibal treats!' -  Weirdlingwolf.
