I had the same reactions as I was watching it. On the other hand, it is consistent with 1st season Kirk. He's kind of a dick. "Not a diplomat" as he confesses in "Errand of Mercy." Indeed, one of the things I didn't like about Pike in SNW in comparison is he's so darned smug and glib. Early Kirk is indecisive, snappish (though he apologizes for it -- three episodes in a row!), and more military commander than diplomat.
