Like its killers, Open House is an effective if predictable and slightly dull psychothriller. There's very little at play other than a pair of serial killers and that girl off've Flight of the Conchords being menaced. Being quite the fan of Flight of the Conchords, I found this quite distracting. In fact, I had to pause the movie two or three times just to go youtube the videos in which she appears. Anyway. Tricia Helfer has some sort of job which involves her leaving the house and Camp Serial Killer Man is a writer. This allows him to spend his days - his Business Time*, if you will - torturing poor Rachel Blanchard and murdering her window cleaners. Open House is the sort of movie in which a lot of innocent bystanders get murdered for no other reason than to amp up the bodycount. It's neither noticably bad nor remarkably good. The acting is fine, especially from Blanchard (the most beautiful woman in any room*) but not enough around the board to make this rise above STD dross. Although it does give me an excuse to post this, which is always nice:
