E.g.: the illogical irrational hyper-emoting vulcans.

Uh, Vulcans have always been illogical and irrational. This is partially because the writers tend to be bad at basic logic, but Trek has a looong history of Vulcans being pompous, racist assholes that are irrationally obsessed with tradition to the point they made it a de facto religion.

They are usually stone faced while they do it, though.

the actors including anson MOUnt acting was so wooden, its not even believable, lol. of course they always tease with the more interesting romulans and then drop them the next season.
