That’s another point I forgot to make. A very vocal group of fans have been complaining that they want Trek to be more episodic, and that’s exactly what they’ve done this season. You could argue there are continuing threads rather than arcs. This feels like a regression to me. The streaming age really needs solid arcs to keep viewers hooked. I’m a little disheartened that the producers probably think they’re just giving the fans what they want. It’s not what all the fans want, and it may not be what the show needs. But, we will see. I’m optimistic for a tight season finale that will pull the season together cohesively.
Yes. This season of Discovery seems less serialized than Enterprise's third season, TBH.
Unlike some others, I don't absolutely require serialization in order to be engrossed with a show however. I think it's important to have long-standing character arcs - to let characters grow and change over the course of a season, and a series. But there's no requirement to make the season about one big thing in order to be enjoyable.
But while I think Discovery has done better character work this season, there's not really definable character arcs. If anything, it seems like regression from most of the characters. Going through the cast:
MIchael: A completely calm, centered person by the third episode due to the one-year time skip. Then she has some sort of crisis of faith regarding her role in Starfleet. Then she gets better. Now she's the same as she ever was.
Saru: Starts the season as a seemingly well-put-together captain, and then inexplicably loses his sense of judgement in the back half.
Tilly: Thrust into command, seemingly fails. We will see shortly if she has any growth this season. I'm worried there's not really enough time for her to go up a level.
Stamets: The father-daughter dynamic he develops with Adira is honestly great - a highlight of the series that brings out a new facet of his character. But then similar to Saru he just falls apart in back end of the season for inexplicable reasons.
The character with the best, most coherent character arc of the season -
Book. He starts off a loner rebel, and becomes converted as a Starfleet true believer. It's kinda like watching Nog's arc in miniature. I'm sure he's gonna die this week, but I hope he doesn't have a last-minute heel turn or something.
