This movie is a disjointed abject mess. I only watched it because it was Australian made and they can make some decent horror movies. This is clearly not one of them.
Right off the bat you can tell the movie had no budget. And it shows. It's very cheap looking and poorly directed. The writing is totally all over the place as well.
But there's the acting -- actually there is none. The so called "actors" are quite imply HORRIBLE. They can't act. Especially the lead blonde. How did they cast such a bad actor?
The only thing she has going for her is a nice pair of legs. A quarter of the movie is over before she gets locked in the demon apartment and by then you're just wishing she sees her end so you don't have to watch any more of this abomination.
