One last thing re: Roswell and Legacies. Mark Pedowitz & his team at The CW had the class & grace to warn the shows that they might not survive, even if The CW wanted them. Because of that, the season finales of both shows were carefully crafted to also work as series finales.

-Some took his advice (Charmed, Legacies, Roswell) while others hedged their bets (Legends of Tomorrow) and ended on cliffhangers.
