Some good, some not so much. I was leaning towards a slightly higher rating, mostly based on DaFoe's superb performance, until the ending. That lowered the rating a notch, because it really didn't go anywhere for me. I am still not sure what the ending was meant to mean. DaFoe's acting does make this film worth watching, however. He does a remarkable job of slowly showing the devastation to both mind and body of being trapped in what appears to be an impossible situation. Sadly, though, many of the extreme situations he faces do not seem believable at all. On top of everything else, a number of unanswered question arose, such as why his accomplice, whoever the heck that was, did nothing to help him. Overall, an okay film, but definitely more fantasy than reality.
