The cursing

It is a single curse word.

the attitudes

Way too vague and I’m not sure what you mean

“Hollywood dark mode”

Which is a visual and stylistic choice to represent something specific in the story that changes as the story changes. Season 2 onwards is incredibly bright.

the crass timing

Again, incredibly vague and I have no idea what you mean

oh god the Klingons… they look like emo versions of Nosferatu

Which are overridden for the second season where they look way closer to normal.

See this is stuff that the video is explicitly talking about. A lot of complaints made about Discovery that don’t seem to be based on anything. The Klingon look I get and the visual dark look of the show I disagree with but get. Everything else though? I’m just not sure where it’s coming from.
