"Sinthia the Devil's Doll" was my first acquaintance with the oeuvre of Ray Dennis Steckler, whose other horror movies do enjoy a modest cult reputation. Nobody claims that titles like "The Incredibly Strange Creatures Who Stopped Living and Became Mixed-Up Zombies", "Rat Phink a Boo Boo" or "The Thrill Killers" are masterpieces of the genre, but supposedly they hold some kind of irresistible charm and entertainment value. This is NOT something that can be said about this film, however. Maybe it's my own fault and I should have chosen a Steckler movie where he actually uses his own name on the credits instead of an alias, or maybe and most likely it's just a seriously retarded film; period. The best aspect about the entire movie is the play upon words in the title. The lead girl's name is actually Cynthia, but Sin-Thia is pronounced exactly the same, so there you go. Clever, huh? "Sinthia, The Devil's Doll" is a typically late 60's Sexploitation movie without anything that even remotely resembles a plot. To compensate for the lack of substance, Steckler attempted to insert wannabe controversial themes (a teenage girl in love with her father) and psychedelic hallucination footage (an orgy with the Devil himself). The finished product is far from exciting, just plain boring and irritable. The film opens with a flashback of young Cynthia killer her parents and setting fire to the house (off-screen, obviously) because her beloved daddy treats her too much like a daughter instead of a mistress. Fast forward to six years later, when the adolescent Cynthia visits her psychiatrist who intents to find out what exactly happened that night. From then on, "Sinthia" is one long and incoherent hallucination sequence that does not seem to end. She endlessly wanders over secluded beaches, descents into hell and has sexual conversations with Lucifer himself. For all you cult-fans out there: Lucifer is depicted by Herb Robins, who also co-wrote the script (what script?!?) and went on to directed the oddball 70's flick "The Worm Eaters". The sex footage is beyond dull and Shula Roan in her first and last major film role ever isn't even attractive or voluptuous or anything. Personally, I fell asleep multiple times during this short movie but I couldn't even be bothered to rewind and see what I missed. One to avoid, there are so many better exploitation trash movies out there to discover.
