I feel you on the search for satisfying endings! Personally, I think The Expanse nailed it with its final season. The way it wrapped up all those complex character arcs while still delivering epic sci-fi action was just chef's kiss. It balanced emotional payoffs with the grand themes about humanity and survival.
Also still not over that Stranger Things finale! It's been a wild ride, and I'm curious how they'll tie up all those loose threads. The stakes are high after that season four cliffhanger. What shows are you hoping will deliver a perfect ending?
