I'm not going to get into the whole
Enterprise debate. Not
again. But as for the appearance of the Klingons -- as Ronald D. Moore says in the fifth season DVD set for DS9, the makeup changed. If it weren't for the "Trials and Tribble-ations" episode, we could pretend the Klingons always looked the way they do today. But there's
no explanation I've ever heard for why they look different now that makes any real sense. Sure, they could have been surgically altered. But
why? To what end? It just strains credibility to the breaking point. They weren't a different race of Klingons, because we saw Kang, Koloth and Kor on DS9 and they looked the same as all the other Klingons do today, and not as they did on TOS.
That's why Worf's remark about the difference in their appearance is
not a "lame explanation" -- it isn't an explanation
at all, nor was it intended to be. I thought it was
brilliant. I just imagined all the other fans (and I did the same thing), watching that episode for the first time, sitting on the edge of their seats and thinking, "Now they're going to
have to explain why the Klingons used to look different! Finally, the mystery will be solved once and for all!" And then getting Worf saying, essentially, "None of your business." Just brilliant! I laughed so hard I missed the next three minutes of the episode.
