Screaming Silence.
I know Worf touching a little on the differences between the OG Klingons and TNG Klingons during a DP9 episode. Don't remember if he hinted at disease or genetic engineering gone wrong. Basically ended with him saying they don't talk about it with outsiders. But I do agree, TNG Klingons with there custom crafted language (that you could learn at Harvard for a short time) is where it's at.lol. Not what I imagined. But I mean, the OG series Star Trek was pretty easy on the makeup with their klingons.
Like I had stated before, TNG Klingons are where it's at for me, personally. And I guess DS9 they were pretty much the same look/attitude.
