Filmmaker Jared Cohn's underpopulated thriller is an (alas) irony-free throwback to the 1990s "from hell" mini-genre of would-be psychological shockers that proliferated because of Fatal Attraction (plus Single White Female and The Hand That Rocks the Cradle), centered on manipulative lunatics, driven by lust/envy/revenge obsessions, insinuating themselves into hapless victims' lives. One might recall The Ex (ex-wife from hell), The Temp (co-worker from hell), The Sister-in-Law (sister-in-law from hell), One Good Turn (old-army-buddy from hell), etc. The logline for this new entry could be "internet-date from hell."
A dismally formulaic narrative is the same routine. Lovesick Mike (Jack Pearson) may look normal but as a romantic partner, he is domineering, parasitic, jealous, and lethally narcissistic. When a girlfriend breaks up with him, he summarily kills her. A month later, chic Jen (Veronika Issa), estranged from her upscale doctor-lover, tries a matchmaking app that pairs her with the same madman Mike, who irritates her by trying to force sex on their first date. Mike, not accepting rejection, lurks around Jen's new house, murdering another would-be suitor and anyone else who would obstruct his relationship with Jen.
It is a standard contrivance in these pictures that, even with frequent mentions of calling the police, the psycho has unbelievable success in slaying people, disposing of corpses, throwing off suspicion, and even charming Jen, culminating in the inevitable one-on-one bloody showdown with the heroine. Mike gets virtually no backstory or explanation (until a climactic soliloquy about his institutionalization and mental-illness diagnosis) or hints of any real existence outside of stalking women. That lends a properly disturbing and paranoid vibe in and of itself, and all the hardworking actors give their lines a sincere demo-reel try.
But with nothing much special about it, the feature is merely an unpleasant, inconsequential, suspense/slasher filler. For what it's worth, there was a 1993 satire of the whole "from hell" genre, entitled Hexed. Little good is said about it. Not recommended.
