Fun, crazy movie with default ambient horror music. Andrea Riseborough (the titular Mandy, and I think Oblivion is due a rewatch) is a hitman who possesses the minds of people who can get close to the target, kills target then self. Jennifer Jason Leigh is her boss, and she ends up going two levels of virtual – so far, so eXistenZ. She possesses Chris Abbott but stays too long, and he begins to see her memories and visit her home and kill her family.
