It is fine that you don’t like it. I don’t really think you will get downvoted for it. I also don’t like LD as much as other people but I think it is fine.

There are many other trek things that I don’t like as much as other people, but in the end there are different parts of ST that resonates with different people.

The thing I like about ST is how realistic somethings from back in the day are. I also like the more serious tone of things, but I think with the popularity of things like the Orville etc you can see that a big part of the fandom was looking for something more light hearted.

Just tell your co-worker that LD is just not for you. I am sure he will understand.
