Yea the whole Spore drive concept using the layer b/w universes to travel introduced in season 1 is some of the best world expansion in sci-fi IMO. The "Terran" captain twist was great. Season 2, Pike became on of my favorite captains. Saru is one of my favorite characters on the show. I like Tilly and Stammets. Personally I have no issue with the Klingons' since we already know their DNA was "changed" at some point to make them look Human(middle eastern), then they kinda "evolved" back into the turtle heads. In this timeline... they don't appear to have altered their DNA to look Human.
