El enigma de la mansión siniestra

A daft, but entertainingly modest low-budget late 70s haunted house variation with horror comic lashings (intentional or not) in what becomes a traditional battle between good vs. evil. Nothing surprises, as no cliché is left untouched, but director Gus Trikonis' able execution is quite well done for what it is. Some creepy or outrageous moments and there's a solid cast led by the ever-reliable Richard Crenna, as he plays a psychologist along with his wife (a doctor) buy an abandon mansion (which does have something of a gloomy past) to hopefully restore to use as a clinic. So some friends and students of his go there to help fix it up, but unknowingly to them a devastating satanic force is unleashed and they find themselves trapped inside trying to survive.

The raw atmospheric make-up emit's a dominating presence, from the grand vast secluded mansion to the eerily placed music score, imaginative camera placement and cue in the cackling evil laughter of the evil entity. It constructs an ominously nightmarish strangle-hold, as it grows claustrophobic but at the same time the whirlwind becomes a random schlock-fest with its climax being the tip of it. It's not as unnerving as it could have been and the ending it feebly done. The story dynamics are old-hat (a stormy night) and it's slow to get going with some plodding opening dialogues, but soon that's made way for impulsively staged deaths / encounters --- consisting of spirit manifestations, possessions, fires, self-mutilation and bodies being thrown about. When these strange occurrences transpire, it's even mentioned for no one to go anywhere on their own, but do they listen… of course not. The dedicated cast also features lively performances by Andrew Prine, Joanna Pettet, Cassie Yates and a memorable sequence with Victor Buono.
