My Two Cents
First off, I should mention I'm only a casual fan of Star Trek, with no great knowledge of the ST universe - though I've seen some of TOS and all of the films (except Beyond), all of TNG and DS9, many of Voyager and Enterprise episodes. That said, here's my assessment:
Frankly, I was kind of bored with this, unimpressed.
The opening wasn't that exciting. How they made a pattern in the dirt for the ship to see where they were, would that actually work? If their ship can't detect two humans, how could they detect a (rather shallow) pattern in the dirt? What about the creature that jumped out of the well? It was a missed opportunity for some well-need action, in my opinion.
I didn't care for the look of the ship, or the way it was shot. Too dark, you could really get a feel for how it was laid out the way you could if it were more brightly-lit. But again, this is just my impression.
Worst part: The Klingons. I just did not like how they looked. Certainly not like any Klingons I've seen before.
I have to admit that I was confused about the time period this took place in. I was expecting it to take place post-TNG-DS9-Voyager. I don't know my Star Trek well enough that when I heard the year that I knew when was in the timeline. But then we see Sarek, and I thought, "Wait a minute, isn't that Spock's father? He's young!" I subsequently read that this show is set 10 years before Kirk, Spock, etc. Why did the makers decide to set it then? At least with Enterprise, we knew that show's purpose: To show the very beginnings of Earth's travels into space exploration, the early years of Starfleet. For what purpose is Discovery set 10 years before TOS?
When the Discovery finally had its confrontation with the Klingons, I found it to be rather ho-hum (individual experiences may vary on that subject), not rising to the level of excitement we might expect from a ST series.
I don't want to be too quick to dismiss this show, and would watch the next episode but it's being held hostage behind a CBS paywall??? Frankly, CBS is just dooming their show doing that. Considering how little enthusiasm I found for episode 1, I'm not about to pay to watch more of the same.
