Let's go down the list a bit more.
We had Rios, who was introduced as the rogue-ish guy. So Rogue that his first moment on screen is manually pulling shrapnel out of his shoulder shirtless while guzzling some liquor. Yes, this is written for a pre-teen level of understanding.
Then we have Raffi, whose relationships with Picard is bizarrely out of character, and around whom they threw random emotional bids to see if the audience might respond (her problems with her son, just have a cheap scene; her conflicts with the captain at random times which just seem like menopausal mood swings unrelated to the plot; now her sexuality, because all else failed to create a character).
How about 7 of 9, who is nothing but a psychopath now? They fetishize female violence so much that she is meant to hold our gaze somehow, when she's at best a simple, bitter character whose outright murdering in one scene is shot so as to suggest we are witnessing a badass triumph. TNG would never have this character on screen. She's a reject actress from the worst days of Voyager in their awful Borg arc.
Who else? Jurati? None of her writing makes sense. Perhaps one the weirdest things is when she said if she's never been in space, because I guess only starfleet fly around in this timeline. Any high-level scientist would have attended conferences primarily on space stations and other planets, this was well established in the old shows. That line alone was so confounding, the writers don't even understand the basics of this future.
Picard is no longer the same character. And it's not a smart development, it's that Patrick Stewart can no longer act. He has no idea what the lines mean or what scene he is in, painfully so.
Bringing Q back to die was a horrible mistake, nonsensical if you know the continuum. There isn't even a good explanation, when we know in the past that Q never had to deal with mortality. When he turned human in one episode, it was the first time he faced even the possibility of death and he discussed it at length, because Qs do not die.
Brent Spiner was great at Data, but bringing him back as 4 or 5 Soong family members just shows how poorly he does with other kinds of characters. If they'd been smart, surely B4 should have been activated with his memories, keeping closer to Data's style, but of course we're getting the nauseating over-hammed acting as Lore, which no one wants to see again.
You can keep going all day. There isn't even one decision this series has made which raises it above the worst level of SciFi I think I've ever watched for more than 5 minutes, in more than four decades of life.
