The lore is deep with Brain Damage, as it's revealed that Aylmer has had a long and checkered past throughout history. It's this attention to detail that really sells the entire experience, even if it's all gobbledygook, it makes sense in the moment and adds to the menace of the little parasite. The drug it administers is highly addictive, giving the movie a bit of "This is your brain on drugs" undercurrent that's much appreciated. Perhaps if this film was shown in schools instead of those dull anti-drug PSAs, kids might take addiction seriously, because holy moly does Brian get addicted to the blue juice hard and fast.

This addiction leads to some extremely inventive kills that were originally edited out of the initial theatrical release due to their graphic nature. One in particular stands out above all else - the infamous "fellatio" kill! Censors originally balked at this insane sequence but it's one of the best parts of the entire film. Brian and Aylmer hit up a local club and meet up with a girl who just wants to have a good time. Brian, high out of his goddamned mind, takes her out behind the club to get frisky, but upon unzipping his pants out pops Aylmer and well, he gives new meaning to the phrase "getting head."
