Other than cult classic
Event Horizon (1997), schlocky sex driven Lovecraft adjacent/inspired flick (albeit a terrible one), there hasn't been a breakout adaptation of HP Lovecraft's works or anything inspired from the Cthulhu mythos/universe of blisteringly terrifying and brain shattering horror fiction.
Everything that so far that I've been aware of that has been produced falls under the direct to DVD trash (with cheap production values and insanely poor acting and creative choices that would embarrass James Nguyen, the Frankenstein creator/director of
Birdemic, one of the worst films of all time.
Okay, Netflix's Stranger Things definitely has been highly influenced by Lovecraft's work. But anything else? Mainstream? Or relative popularity or at least cult status?
