One of the joys of Devanand Shanmugam's film is that it begins so steadily, even sedately. You might even be put off by this, but stick with it. Events turn progressively darker, even if they never reach the wince-inducing depths of Mark's aspirations as a stand-up comedian (don't worry, he's supposed to be bloody awful). Mark (Michael Lieber) is a bit of an idiot, and, as is often the way of things recently, the girlfriend, in this case Jill (Loren Peta), provides the practicalities and the backbone of the relationship.
So strong is she that when the couple's new landlords, Henry (Christopher Craig) and Josephine Baker (Antonia Davies), prove to clearly be up to no good, you're surprised she doesn't cotton on sooner. Whatever, this tightly written chiller becomes progressively more weird and genuinely disturbing - nasty, even.
Another joy is the unpredictable quality of the ongoing story. You truly don't know where it is heading, but get quite a jolt when it gets there. My score is 8 out of 10.
