Nope, haven't gotten around to it yet.
hopefully you'll enjoy it, i think it was entirely in keeping with what we have already gotten from the creators,, In the case of Charlotte,, as you already know from S2--- I mean, how can you get better then this for a character arc?:
Before we jump into the nuts and bolts of season 3, it’s important to understand that there is really no way to conclude a story like this in a way that would be satisfying in a normal way. The reason for this is because “Dark” is full of bootstrap paradoxes. That’s the term that describes, to cite one example from the show, how Charlotte could be her own grandmother.
There’s no way to resolve this paradox, because it’s a self-contained loop. Charlotte had a daughter named Elisabeth, and then Elisabeth had a daughter named Charlotte, and then baby Charlotte was brought to the past and became the original Charlotte. There’s no beginning or end of this sequence. And if you’ve watched “Dark” all the way through, then you know it’s full of these sorts of loop
and i loved how there was none of the typical time travel stuff like: "omg, there are two of us (the same person) in the same time, the world is going to explode!!!"
just some intense time travel and on point drama that delivered the plot... making it seem as if its leading you to a easily expected ending--- only to not
i, can only see one issue, which i wont post until you have finished, but its not a big deal
