The appropriation of Mary Sue

OK, so seriously, we have another trailer for The Last Jedi, and I'm just starting to get nervous, because we spent how long a year and a half ago trying to convince people that Rey was not a Mary Sue, and I'm about ready to cut something (ianimate) because I'm too busy being afraid of that starting again t o be excited.

Rey is not a Mary Sue. Batman is not a Mary Sue. Mary Poppins is not a Mary Sue. This is especially true of the last two because their names are in the titles of the canon. Not Sue.

The only acceptable "canon sue" is Jonathon in the Buffy episode Super Star: he was a better fighter than Buffy, better at Magic than Willow and Tara, and knew more about the things that go bump in the night than Giles. And the less said about Willow and Tara's collage the better. However, this was deliberate: Jonathon was literally taking the best of everyone to make himself cooler, it was magic. And in the deft hands of Jane Espensen it makes for damn fine television.

Going back to Rey and Batman though, they don't take anything away from the main characters because THEY ARE THE MAIN CHARACTERS and therefore aren't sues.
