Oh, next gen is great yeah, is the one with picard. If i were to recomend a series to you, Id tell you to watch deep space nine, though : p Its my favorite, it focuses on a space station instead of a ship. And the story revolves around conflict between different species of aliens. The story of ds9 is more exciting and energetic than the other star trek series.
Next generation is cool too, a little slower, but it also has great characters and fun stories. Its definitely a close second for me : p I think youd like ds9 better though, haha.
I'll check out DS9 whenever I'm able to find it, and I have only just watched commercials of next gen when growing up haven't watched it just yet. I like the idea of Star Trek being a lot more energetic since a lot of series I've found tend to be more about like political roles and space patrol of the universe kind of thing aside from the very quirky original series with William Shatner(which sounds funny to watch later haha.)
Also I was wondering since you've watched quite a bit of episodes how you felt about parodies in general and stuff? Have you watched Galaxy Quest? It apparently parodies a lot of sci fi stuff mainly Star Trek I'm holding off on watching it till I get to watch some Star Trek series to understand it though.
