I've never really watched any Star Trek. Where should I start?
Oh yikes that’s a difficult one with almost 60 years for you to catch up on. Next generation was my starting point but back then you only had that show and repeats of the original series. Try next generation first (pilot episodes encounter at farpoint pt 1&2) but mix it up a bit and watch episodes of the original series in between because they do make references to the past show.
