King Arthur/YMMV


 * The French Love Arthur: Seriously. Half of the classic stories come from France of all places. May be in part because British culture ended up fleeing to Brittany among other places after the Anglo-Saxon conquest.
 * To a lesser extent, the Scots, who, while unrelated to Arthur directly (they're Irish and Pictish mostly, with a little bit of British down south) got on the bandwagon as well. They do, however, revise the stories from time to time to make it more favorable to their own national heroes (like King Lot).
 * And then there's the English, of course, but then, it is pretty common for countries to celebrate their deep past while glossing over all the invasions and revolutions in between.
 * The Germans love Arthur too, particularly the Grail legends.
 * Marty Stu: Sir Galahad
 * Sir Lancelot falls under this, too. He was added later by a different author (Chrétien). He romances the queen (a plot point that previously went to Sir Mordred), is better than everyone else in combat, and is best buddies with everyone in the round table. However, these are all Played for Drama at various points in the story, proving once again that Tropes Are Not Bad.
 * Although it has been speculated that Lancelot may in fact have been the hero of a folk tale of his own that was then absorbed into the Arthurian cycle (not unlike what happened to Tristram).
 * Recycled Script: The tale of Sir La Cote Male Taile is pretty much the exact same story as the tale of Sir Beaumains; a lowly servant becomes a knight and is given an insulting nickname by Sir Kay, they go on a quest with a damsel who mocks and degrades them endlessly, they wind up proving their worth and changing the damsel's view on them, and their true names are eventually revealed (Sir Beaumains = Sir Gareth and Sir La Cote Male Taile = Sir Breunor.) Both of these stories are told in Le Morte d'Arthur, so a sense of Deja Vu is inevitable upon reading them one after the other.
