They did before. So I see no reason why they can't again.It's like watching a really great Beatles cover band. They might play an arrangement or medley of the greatest hits that you haven't heard, but you can't expect them to write a new song. That isn't what they do.
It's a challenge to temper criticism where it's deserved. I really like STC overall, but I fear they're falling into familiar traps. They need to get their heads out of being "huge TOS and Trek fans" and think about story. They need to look for inspiration outside of Star Trek just as TOS did. And that might include going beyond their core writing group for fresh perspectives.
I think a lot of fans don't understand this because they get hung up on things they really enjoyed in the past and somehow believe if you revisit those elements then some of that greatness will be transplanted to the newer effort. No, it doesn't work that way. But it is easier to write than trying to craft fresh stories with new elements.
