I rented this while I was staying in NZ and sat down prepared for a love story that turns into something like Fatal Attraction or something. Not at all. I appreciate the plot twists and enjoyed the extreme weirdness. Not horrible but not fantastic either ( in my opinion.
All in all I think the acting was pretty believable, but there are some plot holes (pretty gaping ones actually). However the story is pretty consistent with details from the beginning being carried over through the end.
I will look for movies with the lead actress and this director again in the future.
Enjoyable for those with twisted minds.
