Nothing about these stupid three characters or "raw emotions" is quintessential Trek. Its principles, created by Roddenberry, sticked to even by anti-Roddenberryians like Meyers and maintained throughout the MAJORITY (there are twenty-eighty seasons, not merely three) of Trek by Berman, are.
Well, one can argue that Roddenberry's own approach varied over the years--and, of course, he had nothing to do with DS9, Voyager, Enterprise, and most of the movies.
Me, I confess I prefer the more rough-and-tumble attitude of TOS, and like the way the new movie has brought some of that rambunctious spirit back . . . .
Think of it as getting back in touch with Trek's roots.
