'Grandmother's House' (1988) – Peter Rader.

The gore-giddy 1980s proved to be a remarkably fecund year for inventively off-beat horror, arguably the last truly great decade for idiosyncratic, independently made, wild and woolly murder mayhem, and gifted film-maker Peter Rader and prolific producer Nico 'Zero Boys' Mastorakis combined their not inconsiderable talents for wickedly warped weirdness to creepily create their dastardly conceived adult fairytale 'Grandmother's House', an outrageously original, eerily eccentric, terrifically tweaked, twist-laden, Octogenarian-starring, marrow-chiller wherein two teenaged siblings miserably find themselves sinisterly steeped in the murky midsts of some delectably Grimm goings on at Grandmother's horror House! Settling into this increasingly ominous abode after the sudden death of their father was never going to be an easy transition for grieving younger brother David (Eric Foster) and older sister Lynn (Kim Valentine), and David's innate curiosity very soon gets the better of him, and he disturbingly discovers a monstrous, long-buried family secret that heralds an exhilaratingly explosive climax replete with more subversively head-spinning twists and teeth-rattling turns than Hadron's calamitous collider! Feverish fans of Bob Balaban's similarly skewed 'Parents'(1988) and Matthew Patrick's Gary Busy frenzy 'Hider in The House' (1989) should get an especially perverse kick out of visiting dear old Grandmother's House', but 'Don't Go In The Basement' as she just might not let you live to regret it! 'Some prefer to grow old disgracefully and leave a wealth of good-looking young corpses, since there's still many a good son slayed by an batty old blood-thirsty biddle!
