Man, the creative team on STD is really trying to course correct this season:
Star Trek: Discovery - Season 2 | New York Comic Con Trailer
They’ve slapped hair on the Klingons and are trying real hard to retcon it:
L’Rell explained that the change in the Klingon’s appearance was inspired by the Star Trek: The Next Generation episode “Rightful Heir” and the story of how Kahless created the first bat’leth from his own hair. The idea is that Klingons shave their heads during times of war and grow their hair during times of peace.
It also sounds like they’re going to try and slip in the TOS and TNG style Klingons at some point. Like they should have done last season:
“In season two, you are going to see much different designs,” Hetrick said. “You are going to see different houses you haven’t seen before. One of the most important things to us was that at this point in canon, as we head towards the current version of unification, the houses really each grow up on different planets. It is an Empire, it is not just Qo’noS…We have seen six of the great houses in close up in season one. As we move forward into the next season, I promise that we will continue exploring and unpacking and unfolding that infinitely interesting story of what the Klingon culture looks like on a wider level.”
I’ll be watching out of morbid curiosity. There’s no way you’ll ever convince me this is the Prime timeline.
