My thoughts on this episode, then.
The Good
The Discovery herself - I was
so much more sold on the ship itself seeing it "in the flesh" with proper effects and the tight camera angles. Loved it.
The space shots are still brilliant, I love this aspect of the show, how the uniform starfield is gone and replaced by those lovely views.
Lorca! I really liked this character, a truly different Starfleet Captain. Lots to pick apart there, what is his motivation? What are his true morals and goals? It's he the Captain of a science ship at war, as he tries to tell Burnham, or is he a warmonger on a science vessel like Stamets seems to think? Jason Isaacs did a great performance, too.
The sets - in particular the mess hall and ready room are lovely sets, detailed just enough, with some callbacks to TOS (such as the food slots and the colourful data minidiscs) and some neat designs technology wise, combining buttons and hi tech holoscreens.
The mushroom story - I'm quite taken by this aspect of the story, it's much more interesting than the Klingons arc. Yes it's nonsense, but lots of Trek tech is total nonsense so that doesn't bother me much. I like the peacetime applications of it and the fact it isn't a weapon or an ancient something-or-other to find á la SG-1.
Lorca's attitude to Burnham's past. He, in-universe, had many of the same observations that we had here about Burnham's actual culpability and the ambiguity of whether she was actually right to do what she did. That's a level of grey which Star Trek has struggled with in the past, and it's nice to see that we are getting something more complex.
Saru and Burnham's relationship continues to be a highlight.
Dialogue was improved. Not great, but better.
Cadet Tilly is finally a cadet who actually acts like a new recruit instead of a genius or a twat. Now we just need an Admiral of whom I could say the same
The Bad
The shoot em up on the Glenn was pretty generic, and the giant mole thing was a pretty standard jump scare monster. I was glad this sequence was over quickly.
Landry. Ugh. A horrid cliché of a character. I hope they give her some depth or she dies horribly and quickly. Calling prisoners 'garbage' and 'animals' is a bad caricature which is outdated by
today's standards, let alone Starfleet's.
Stamets didn't get much to do but complain and deliver exposition. I'd like to see him have a bit more to sink his acting into, especially since he is bound to feature heavily in the arc.
Overall
Enjoyed this more than the pilot, considerably more of interest and more depth to the story and characters. Really liked Lorca, Burnham, Saru and Tilly. Needed a stronger episodic story, but I liked this one. 8/10.
