It isn't that simple. BSG brought in enough ratings that with the prestige it lasted four years and spawned two spinoffs (don't count on none others). DW went its own way yet listened to the fans, but listened

. Ditto LOTR.
And no matter what anyone does, somebody will complain. So what? When did everybody among the fans of a franchise like all the entries in it? Good God, even folks who adore The Hunger Games
, half of them hate the third book!
