wasn’t a fan of Clara. Best grouping was River Song, Rory, and Amy Pond during the Matt Smith era.
Clara was certainly one of the better companions of the rebooted era, IMHO.
Billy Potts was by far the least relatable of the companions, up until the Whittaker years in which the entire show just became unwatchable across the board.
I’d say since the Reboot, the top companions would be not in any particular order.
Rose Tyler, Martha Jones, Donna Noble, Amy Pond and Clara.
There were other noteworthy ones, but those would be the best.
I think the father and stepson during Whittakers years, had promise, but that entire era was just bad across the board, and the indian woman companion was just terrible... and I mean that as the character, nothing against any of the actors or actresses during those years, they did the best they could with the crap writing they were handed.
