Malignant (2021) review

Madison (Annabelle Wallis, doing her best Isabelle Adjani impression), who has a history of miscarriages and lives with her abusive husband Derek (Jake Abel), gets attacked one night by a dark creature capable of controlling electricity and her husband is killed, which leads the police to investigate ... and wonder if Madison's the suspect (though she adamantly denies it).  For the first two thirds, it's your traditional Woman In Peril movie - a combination of Basket Case, Possession and J-Horror (like The Ring) - with more of a jokey (and not really scary) tone to it, before becoming really and truly dotty right near the end when the "twist" is revealed, which gives the last twenty minutes or so a truly silly and bloody jolt.  Of course, something like logic really doesn't apply to this kind of movie, and the ending gives a hint that future installments are possible, but this hybrid creature needs to be locked up forever.
