I was never really a fan of the original series. I like the characters but I have a hard time getting into a show that is so old.
I have seen every episode of The Next Generation, and most of Voyager and Enterprise. I just started watching DS9 for the first time.
I know every episode of the original series (TOS, TNG and Voyager and DS9 are on TV in Germany), but I`m not a fan of TOS. Yes, it`s too old for me.
I like TNG (I know every episode too), but only Voyager made me a Star Trek fan.
I tried to get into DS9, I really did, but it didn`t happen.
I don`t like the characters and I don`t like the storys. Sorry.
