Brilliant season; perfect finale. Really nailed it.

I completely disagree. Season 3 was a tremendous letdown. The first 3-4 episodes developing the other world were very dull, and offered extremely little outside of setting up the underwhelming conclusion.
The first two seasons were fantastic, but the third got messy. It also lost most of the poignant moments/scenes that made season 1/2 so great.
We end up finding out there's a third world, and that's the only one that's left, and we see all of about 15 minutes of it. Not to mention most of the characters they spent so much time developing no longer exist.
At the very, very least, they should've played a very moving 6-8 minute song and showed every integral character disintegrating. That was a big miss.
I didn't like the entire direction of season 3, but sticking with it, I have a far more compelling ending.
The entire point of the show that they beat us over the head with was all of their destinies were doomed to forever repeat, and that "the end is the beginning, and the beginning is the end".
So here's your ending. Martha and Jonas suddenly appear on that rainy road, and that is what actually CAUSES the accident in the original world, which then leads to everything we've seen. The final scene is the opening minute or two from the first episode, Jonas wakes/sits up startled, Adam narrates "The end is the beginning, and the beginning is the end.", roll credits. That would've been epic.
