okay, yes, the doctor and rose are very orpheus and eurydice. yes, in both stories the love was not enough to stop the tragedy. yes, what ultimately mattered was the love and not the tragedy. yes, both get their eventual happy endings through a death and rebirth
BUT i feel like people get it mixed up. the doctor isn't orpheus. rose is. rose is always the one fighting through hell and high water for them, the one who has, multiple times, faced impossible odds to get the doctor out of proverbial hell. the doctor's position as eurydice is acceptance of his fate. that he deserves his place. but he sees orpheus fight for him and even though that doesn't change things, he knows he is loved.
the game station? bad wolf? orpheus and eurycide, but orpheus succeeds. krop tor? the satan pit? how much more obvious can you get? orpheus and eurycide but eurycide climbs out of the underworld.
but see, then you get doomsday. then you get the tragedy, and although it seems like rose is eurydice dragged to hades, you just have to ask: who fights to get back? who gets their "wait for me" in the form of missing stars and dimension cannon jumps? rose. she's orpheus, jumping universes with her own song of love leading her back to eurydice. and the doctor does turn around on the street (very orpheus, i know. the comparison writes itself) BUT then he dies! he gets shot! back to the underworld!
the metacrisis regeneration is, as mentioned before, the final death of orpheus and the reunion of lovers in the underworld. because everyone seems to forget that part is possible, if not thinly implied in ovid's "metamorphoses".
and maybe that does make the doctor orpheus. maybe they're interchangeable. i just love finishing the story of orpheus and eurydice with "but the love was there. but looking back wasn't the end. but there can still be hope after tragedy" because that's ultimately what it's all about.
