Ahoy-hoy, people of Star Trek BBS. My name is Ole Christian (Yes, really). My first Star Trek was Voyager when I was younger, which I was not a huge fan of. Later, a friend of mine made me watch The Original Series and I was hooked. I also like TNG a lot, and watch the occasional DS9. Voyager and Enterprise much less so.
It's always this way...really. I know I'm biased but TOS always seals the deal or turns people on to the whole thingamajig. I'm not sure if I've mentioned this today but I love Star Trek The Original Series.
