but it's worth it for the shots near the end of Arthur/the Fisher King, now healed of his wound by the Grail, riding through an orchard in bloom (the land of course, has healed with him)

Oh, nice. And that adds it to the short list of films which retell the story of the Fisher King, aside from the famous one.

Also, it's probably the only version of the Arthur/Guinevere/Lancelot triangle I find genuinely tragic rather than soap-opera -- each of the three people involved comes off as likeable and quite sincere in their feelings about the other two.

I can how that would be compelling and refreshing. Wanting to yell at everyone for being an idiot is not as much fun.

(What do you find wrong with other depictions—they could be solved by poly or at least conversation?)
