I think a lot of the cringey dialogue and hokey ass performances is a result of unnecessary swearing. In something like The Wire, it seems natural and actually enhances the scenes. In Westworld it comes across as forced and makes perfectly okay lines come off as terrible.
Like when Tessa Thompson goes, "We've seen glitches before.But this...thus is fucking breathtaking." That line delivery actually sounded like it was sabotaged by that swear. It just sounds like they're trying to make this corporate world seem edgy and cutthroat. And every time someone needs to show that they're angry or baffled, they swear a lot. I dunno if HBO has a swear quota, or the writers feel they're not taking advantage of HBOs looser standards for profanity, or they feel like viewers won't take a sci Fi show seriously if characters aren't swearing and fucking all the time. But it is jarring and stands out and kinda takes me out of the show.
