I like LD because of its sense of humor and Trek deep cuts.
The LD characters are much more like “real” people than the other Trek series to me. By that I mean: TNG was full of people that I would admire and look up to if I were on that ship. LD has people I could see myself becoming friends with. But maybe that opinion reflects the age I was/am when watching each of them.
If you aren’t a fan of the humor, and don’t get the deep cuts, then I could see why you aren’t finding much to like about it.
