I'm still disappointed that SNW Klingons sound like a boy band.
They're supposed to sound like TNG Klingons. Everybody sang in the squeaky range. A variety of voices would have been nice. Ethan Peck's a baritone. More than one note of Spock's big number could have been there.
I dunno. I see Klingons as extremely old-school, culturally. They treasure old ways of fighting (bat'leth, qutlutch), worship (Kahless, dark, candle-lit spaces), being (honor bordering on chivalry, belonging to the house of one's father), and singing (manly voices--Michael Dorn even lowered his speaking voice for TNG). For me, hearing Klingon high-pitched voices during a crisis was analogous to hearing "Eek! A mouse!" It was funny, but I'm still experiencing cognitive dissonance.
