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.
Me and my mate were expecting Klingon opera, but the sound cloud rapping (or whatever) was so unexpected it really made us laugh. I think they played it really well and I'm not sure I'd want them to change it
