DVD & Blu-ray review: American Mary (18)

Katharine Isabelle convinces as Mary, a budding surgeon who stumbles into body modification to make ends meet in this grisly horror from the Soska twins, aka the Twisted Sisters.

Mary's rudimentary slicing begins on a hoodlum and a woman who wants to resemble a doll. However, things take an uglier turn after a lecturer sexually assaults Mary and she applies her new skills to a bit of torture and some increasingly freakish procedures. There's some gamey B-movie-style acting and a weaker second half, but this is still an accomplished, inventive slasher.
