Atmospheric is the first word I'd use to describe this movie. With the thick rolling fog, deep forest, dark castles and rocky seacoast; this movie delivers on locations. The filth is fantastic. When characters get dirty, they stay dirty. Their clothes look worn. When Gawain falls ill, he looks it. There are sweat stains on most of the cast. I don't know about you guys, but I appreciate touches like that.
In this version of Gawain, everything, no matter how bizarre or with a touch of silly, is deadly serious for the players. From the moment the movie starts it wraps itself in the period and surreal imagery and grimly marches on to a very well done conclusion.
Though it gets a lot of bad reviews, I genuinely like this movie. In fact, I like it much more than the remake "Sword of the Valiant"-- whose characters come off as not taking their environment, or each other, seriously.
