I saw James Wan’s Saw and a few sequels, then slept on his sequel-spawning follow-ups for whatever reason, maybe the same sense of “anything popular can’t be good” that made me skip the Final Destination series. This one is inventive and completely loopy – and seems to invite sequels, though our hero is gonna get hella locked up after slaughtering an entire police station.

A research hospital in 1993 has a patient who drinks electricity and broadcasts its thoughts over radio. Then present-day Maddie has an abusive husband who conks her head against the wall and is later killed by unseen forces – the same forces that start hunting down the scientists from the opening scene, and tie up some random tour guide in an attic, all of which Maddie sees happening in a psychic daze. Maddie’s sister (of God Bless America) investigates dark family secrets while detective Shaw (of A Bread Factory) tries to help and detective Sasstalk (of She Hate Me) doesn’t help at all.

L-R: Shaw, Sasstalk, Sister, Maddie:

If you hadn’t used the movie title to piece it all together (I hadn’t), Maddie’s half-absorbed conjoined twin was awakened by the head injury and is taking over her body to do murders (and that’s their mom in the attic). I guess the twin’s radio-control mind-power gives it incredible fighting skills in her body (this is an upgrade to Upgrade).

The names in this movie’s cast are more upsetting than the horror creature. Maddie’s real name is Annabelle, and starred in Annabelle (but not as Annabelle) while Maddie’s sister’s real name is Maddie, and the dead husband played Mike Love in Love & Mercy.
