A medium and her two lesbian friends spend a fatal weekend in the sinister home of a woman and her disturbed son.The woman enjoys painting and stabbing her victims in the crotch during sex.I have seen "Sexo Sangriento" aka "Bloody Sex" in Spanish,so the plot wasn't fully understandable to me.One thing for sure:this Catalonian horror film was made during the time of the pro-Franco censorship.It mixes lesbian sleaze with satanic imagery and bloody axe murders.One of the killings is especially misogynistic:the unfortunate lesbian victim is stabbed in the crotch with a knife during sex.This scene reminded me similar moment from infamous "Giallo a Venezia" due to its savagery.The film is loaded with full-frontal nudity and the main music theme is strangely "Dawn of the Dead"-ish.It ends with Algernon Blackwood's quote.7 out of 10.
