Serving as the Season 2 finale, “The Casavin Curse” is a whirlwind of campy melodrama, incestuous undertones and a twist that manages to be both completely predictable and utterly absurd. It all starts with the kind of scene that makes you wonder how the cleaning staff handles the turnover rate at the Casavin Estate. Gina Casavin (Catherine Parks, Vera from Friday the 13th Part III) wakes up in a trance, surrounded by champagne, pills and the butchered remains of her lover, Tyler. The local police, led by the ever-stymied Lt. Wright, are baffled by the crime scene, even though there’s a literal dagger involved.

Enter Dr. Jeffrey Webster (Scott Lincoln), a criminal psychiatrist who seems less interested in medical ethics and more interested in becoming a secondary lead. He spends the hour trying to convince Gina that her family’s legendary curse, which supposedly dates back to a jilted gypsy named Mirabel, is just a psychological crutch used by her cousin, Nicholas (Joe Cortese), to control her.

The dynamic between Nicholas and Gina is, frankly, skin-crawling. Nicholas is the quintessential “I have half the town in my pocket” villain, complete with thinly veiled threats and a disturbing obsession with keeping the Casavin bloodline pure by moving back to Corsica.

The episode leans heavily into the “he’s the killer” red herring, with the maid, Miranda (Julie Ariola), playing the classic role of the disgruntled employee who knows too much. When the police finally bust in to arrest Nicholas, it feels like the natural, albeit boring, conclusion.

But wait! In the final act, the show stops pretending to be a grounded mystery and leans into the supernatural nonsense. Gina undergoes a physical transformation — presumably achieved through some very affordable prosthetic makeup — and goes on a rampage. The final reveal, where the maid confirms she’s the descendant of the original victim, is the exact brand of “wait, what?” storytelling that keeps this show from being a total slog.

If you’re looking for a serious exploration of mental illness or a tight, suspenseful murder mystery, steer clear. But if you want to watch a show that goes from zero to demon-possessed heiress and still has time for commercials, watch it.
