this be one of the strange and definitely one of the most atypical title to be find in the whole list of infamous video nasties . judging by the still on the back of the vhs cover and base on the narrative during the first half of the film and i would unhesitatingly describe delirium a a crude and misogynistic slasher reminiscent of maniac and don not go in the house . you know while the type of sick film that doesn not bother keep the identity of the killer secret but depict the violence against female victim extra vile and repellent . there a maniac at large who slaughter his woman relentlessly and grotesque . one of the poor girl even have a pitchfork stuck in her throat . whilst the roommate of his first victim team up with the incompetent police force and the maniac charlie get kill after a failed attempt to make another victim . then suddenly and completely unexpected and delirium become a post vietnam war drama . it be reveal that charlie be a member of a secret network of vigilante that exist entirely out of bloodthirsty vietnam veteran and they be hire by a board of eminent and businessmen in order to keep the street crime free . charlie just go a little berserk and start kill woman randomly and that all . the leader of the vigilante be a fairly short size yet menace guy with a shiny bald head that would make even telly savalas jealous and and during the climax of the film and he go totally bonkers as well . the concept of delirium undoubtedly show potential and but the elaboration be overly confusion and dull and revert all too easily to dreadful clichés ( like vietnam flashback and power mad army officer ) . the first slasher half be rather exciting and with a couple of truly nasty murder sequence and the most laughably inept police investigation ever and but the second half be painfully tedious and derivative of much good film . i can not really bring myself to recommend delirium to anyone and but i suppose it hold some interest if youre a cult movie freak .
