You know what might be neat? A Cardassian movie. They're obviously known to our Starfleet friends. Could be interesting to see what they were up to in this century.
Geeez, didn't you have enough of Cardies in DS9?
Kinda, but this would be 100 years before that.
I'm mostly just trying to think of something familiar without completely rehashing ideas.
I mean, we could have a Klingon or a Romulan story. Or we could have another Big Bad Evil Something on its way to destroy Earth that our heroes have to stop. But why do something that's been done a thousand times already?
The Cardassians, while obviously explored in DS9, are a complete mystery in this time period. There has never been a TOS story about them, but this new movie shows that they are obviously known. Enough so that there is a drink named after them in the bar in the beginning.
Doesn't have to be Cardassians. I'm just throwing stuff out there. But it might be neat to see what they were up to in the 23rd Century (without it feeling contrived, like if they were to do a Borg movie or something).
