These are the words of one who is not watching. You're just fault-finding.But it was contrasted with lots of fun and adventure, and a sense that people wanted to be there doing what they are doing. There is no contrast with Discovery which makes it the weakest entry by far in the franchise.
Star Trek's greatest strength has been that it is a platform to do pretty much anything. Discovery, for some reason, decided to discard that particular piece of the format. Instead deciding to do what pretty much every other sci-fi show does, grimdark future.
DSC is the "weakest" entry in the entire franchise "by far"? You can say this after 9 episodes? Because guess what? At only 9 episodes, TNG was objectively a piece of shit. It got waaaaaay better. At this point in their respective runs, DS9 was boring, VGR was aimless and ENT was unsure of itself. DSC has had the absolute strongest first 9 episodes of any spin-off, and isn't "grimdark" (an overused word if ever I've heard one) in the slightest.
