Dating a Trekkie

Hey guys, I am going on a Date with a big fan of the Star Trek Universe. I have watched some movies, but never really got into this universe - I always had more contact with the Warhammer Universe, which seems to be quite the opposite from what little I know about Star Trek.

However, I am absolutely open to getting into it, and with him I will have a good reason to. I would really love to be able to surprise him a little, so are there some crucial things I should know? Like certain movies that were so horrendously bad, that I should not mention them or something.

I also would love if there are some, you know, fun or interesting or even flirty things that he would appreciate. But that's just a Bonus :3

Thank you guys^{^}

Edit: Okay everyone, this is the largest amount of comments I have ever had, I will never be able to answer all xD

I posted an update to the date if you are interested. He did tell me his fav Captain :3

Edit2: It's Janeway guys
