I've seen every episode of every series of Star Trek...including the semi-canonical animated series.
I absolutely LOVE Discovery. In fact, I think I like it better than TNG, which was always my favorite.
Of course, I'm not crazy of how they changed the Klingons. And I'm not too sure about the "spore drive" thing. But other than, fantastic.
I love how this is a continuous story, not a bunch of standalone episodes that one could pick up at any point.
