Netflix's The Crown, which has been streaming since 2016, came to its emotional conclusion after season 6 — but there may still be potential for a reboot. Season 6's finale takes place in 2005, and showrunner Peter Morgan was firm about his decision to keep the show in the past rather than time-skipping up to the present day for the final episode. Though this decision is a sensible one, the Royal Family has seen plenty of TV-worthy moments in the eighteen years since 2005.
