Okay, so I watched the first episode of STD, spoilers ahead.
It was pretty boring and the world-building sucked. Basically, Burnham got herself catapulted 1000 years into the future, already this notion sort of destroys the suspension of disbelief. From a technological angle, they barely made any achievements. Warp technology got replaced by the quantum slipstream we saw in that Voyager episode. Oh, and transporters are now portable (but have a 30 sec recharging time which makes them worse than portable transporters during the TNG era). Other than that, no significant changes, aesthetics have just moved towards a more Apple Store based design which is fucking ridiculous. And of course, Burnham has seemingly no problem immediatly being able to use all the technology and weapons. It would have been way more believable if they got her 200 years into future instead of a fucking 1000, what was the point of that? In that episode where Scotty returns in TNG, he already has no clue about how to use stuff and that's just been 70 years. Apparently Burnham can just pick up an interface from 1000 years into the future and be an expert with it (meanwhile Jay-El can't even push a button on a starship anymore after his retirement in Picard). Ship design, as it was an issue with the Picard series already, is practically non-existent, we never get a full shot of any vessel and if we do it's a complete cardboard ship designed by a 14-year old after watching the Star Wars prequels. Again, it has a pretty Star Wars-ish vibe to it with rouge traders, Coruscant-like cities, mercenaries and the chad Burnham immediately hooks up with even has Jedi powers. Burnham also gets on a drug trip that was supposed to be comedic relief but it didn't came over that way because she just isn't endearing enough as a character. She also gets eaten by a gigantic worm, sadly the thing spits her out again.
They moved on from the grimdark shit of the last seasons and seemingly try to be more optimistic, but it's still full of needless action and shaky-camera shots, again, more like Star Wars than Star Trek. Even in the slower, character-focused moments we get a shaky cam. There is also a scene where Burnham kills 4-5 Andorians and Gorns (!) with in single combat with a weapon she never saw before because it's 1000 years more advanced. Like I have no problem with action scenes but this isn't the fucking Expendebles. Federation is gone which was seemingly caused by some apocalyptic event 150 ago and we don't know what empires or factions exist, it all seems to be gone and only city-states and rogue traders exist. Apparently an apocalyptic event destroyed Starfleet that had something to do with the warp drive causing all warp-powered ships to go down (which would imply that every other faction including the Borg or the Romulans would also be reduced to shambles?). I guess we spend the rest of the season trying to find out what really happened with Burnham helping to rebuild the Federation, as there are sprinkled elements of the Federation still active. Discovery is also coming back and based on the trailer we see how it will get equipped with 32nd century tech, what the fuck the point of that is I don't know. It's basically trying to make an aircraft carrier out of a 15th century Spanish galeon.
My prediction: Less outrageous SJW shit, still Burnham-centered but they'll try making her look less of a bitch (but she's still a Mary Sue), there will be more optimism, but overall it's probably gonna be super boring. Oh, and they are bringing the "Empress" back from the mirror universe, saw her kicking some ass in the trailer.
