It's such a double-edged sword. People complain about showrunners not having multiyear plans, but then they could get pulled at any time before said plan can be carried out, so there's also pressure to wrap some things up earlier in case you get cancelled, but also at the same time leave room for more if you get picked up. They cannot win, IMO.
And yet, of course, like many of you, this is the exact kind of show I tend to be more interested in. Sigh.
