I'm still having fun seeing how they fit the pieces together. To me, it's simliar to the Star Wars prequels. We all know where the characters end up, but there are still stories to tell about how they get there, and other characters along the way. At first, I had trouble accepting the new versions of Chapel, Uhura, and some of the others. Spock I thought was pretty good from the start IMO. Then they started playing with canonical events and stories, but in Season 2 we've seen how things are on something of a trajectory to line up with where things are at the start of TOS. It doesn't even feel like course correction; it's more like they allowed themselves to take a few left turns, then brought things back around, just for fun. I like that. It's an interesting study in writing, and what you can do with the characters but still keep things within canon.
