Ouch!  This s a painful film.  Not because of the way it's made, more because of the subject matter.  It's a beautiful film, cleverly shot.   Think of it as dark, moody and wet.  Really wet.  When you get where it's going you'll probably want to watch it again to understand how you got there.  Then again, as it's so dark, moody and wet, you might not.  The only reason I gave it 4/5 is because I really did get lost along the way.
