SEASON PREMIERE: The fifth and final season of this fantasy series begins, wrapping up the story with Arthur (Bradley James) as King, and with Morgana (Katie McGrath) still out to claim the throne for herself. And last season, she showed that Game of Thrones wasn’t the only show that could revive a dead heroine with help from a magic dragon.
