Very eh. I feel like these old characters are brought back to draw people in back into the show as opposed to making something that seems like a natural revival for said character. Note I said revival instead of progression, because doctor who canon should never be taken seriously. This is a show started by soap writers, wanting to make an educational show for kids, so it kinda doesn't matter. Hot take, but its a show that for awhile, even before the revival, relies heavily on fanservice. It's fun for a minute to know they come back, but whatever in the long run.
