This is precisely the type of film that will garner equal amounts of unbridled praise by the arthouse diehards, as well as criticism (and likely rejection) from a lot of other viewers. My opinion lies somewhere in the middle. I give it 6 stars for the undeniably outstanding acting (obviously, Dafoe)... and Pattinson is very impressive. Something new, yes. Effective at mood-setting, check. The b&w filming, the shots, the scenery itself... even the set, the old dilapidated coastal shack, all excellent. The dynamic between the two characters is raw and real. Is it a thought-provoking free-fall into insanity? Maybe. But... there is a such a fine line between "arthouse", trying something different, leaving much up to subjectivity and imagination, and... just trying a bit too hard. Mermaid labia? Hmmm. But, if part of the definition of a cinematic "success" is evoking emotion, then mission accomplished. Total despair, pity, fear, disgust, and a general feeling of creepery, all there.
