I'll start my comment with my comments on the other comments :) The exaggerated blood spurts is of course ridiculous and I believe was meant to be. This is also what Monty Python parodied, not the other way around as others had put it. And why else would they not? It's transcendental! The actors looking like rockstars ... good thing it's vogue in the 70s and besides, the setting is the medieval period its fitting. What do they want, spikes and high crew cuts? And the complaint about the expressionless actors, I rather think that it is because the drama is in the emotions that the viewers feel for the characters.
And now for my film comments... maybe because I have such a penchant for the medieval period and familiar with the legend that I wholly liked it. And sure I found many symbolisms which I did not understand but I certainly did see the beauty. I loved the way it was filmed, the costumes, the speech, the passion... yes passion! For instance, Gawain/Guvain's devotion to Lancelot and yet remained loyal to the king. I didn't mind the repetitious cuts/editing style as I'm sure they have meanings for which I am still yet to uncover. And gladly I will.
The only complaint I have (yes, I also have a nit-pick but it's minimal *wink*) Lancelot looked a lot older than King Arthur. He's supposed to be this strapping man! Anyway, that is easy to get over with. This film is certainly something that I would love to watch again. Read PTA-fan's review and maybe you'll learn something you may have failed to see. I know I did.
