This movie could have been named "1001 Space Odyssey" for the similarity between Gawain's journey to meet the Green Knight and astronaut David Bowman's mind-bending but equally incomprehensible (acid-)trip to meet mankind's destiny in 2001 Space odyssey... separated by at least 1,000 years. The only thing that saved this film from getting a '1' was the cinematography filmed in Ireland, but the writers needed to lay off the mushrooms.
