Some really excellent TV series have taken more than a whole 26-episode season before they find their rhythm and get properly good. ST:TNG is a classic example, but I'm pretty sure you can come up with others. And some people are claiming that a new series totally worthless, not based on the first series, but based on the first episode? Are you kidding me?
I mean, is it OK if the first episode of a series is unevenly paced, and contains too much exposition, and clunky "tell, don't show" dialogue about who the main characters are and what their deal is? No, no it isn't. We should ask that writers do better, and trust audiences to have the patience to learn who characters are through action over the course of a few episodes.
But just because they don't do those things, is it really worth writing off the next 5 (or however many) seasons of a show, based on one episode? Who does that? What does anyone gain from that?
OK, there's a lot of prestige serialised TV out there now, and you probably can't watch all of it even if you wanted to, so some culling is probably necessary at some stage. But does anyone really have to write something off quite so soon? You can't even give it half a season to try and get up to speed?
I don't get it.
