I think it’s the different humor and visual style case. And that’s ok. I don’t think you need to understand the many Trek injokes to like it- I know people who don’t know Trek and enjoy LD.
What I find interesting is that you feel the characters are cynical. I was quite suprised how endearingly idealistic the characters were, despite being written as flawed. They always make sure to do the right thing and they try very hard to better themselves. There’s a lot of character growth involved, which I much appreciate.
During the first two episodes, I also found the characters hyperactive. By the third one I adapted.
