Some people might be happy to know that the characters won't be like Rick and Morty level of sillyness. The main characters are still Starfleet officers, they will be professional.
He tells Slash Film that there are some things from that show that you can't get away with when you're writing for the Star Trek universe. "A big thing that was important to me was figuring out how do we comedically access these characters," McMahan says. "How can these characters be funny and not break Star Trek? You can't have a Morty in Star Trek. You can't just have a stupid person in Starfleet, otherwise it breaks the aspirational paradigm of what humanity is like in Starfleet. So our leads are foils for each other, but they're very much ingrained in Star Trek."
On the use of comedy:
McMahan also had a message for fans worried that a comedy series doesn't fit into the Star Trek franchise. "Star Trek has always had comedy in it," he says. "Every series of Star Trek has funny characters, funny episodes, and those always live in the B-stories for the most part. That, to me, is what I love about Star Trek. So it's really taking that aspect of it and letting that shine. I can't wait for you guys to see it, because it's one of my favorite things I've ever made. It feels like it fell out of another dimension in the 90s where they were making a funny Next Generation era show."
There are character breakdowns in the article that I didn't quote here.
Also, it is a 'canon' show, for those who care about that kind of thing.
