‘Better Call Saul’ breaks in the right direction with its satisfying series finale

After six seasons building toward Saul Goodman’s foreshadowed fall, “Better Call Saul” presented its final chapter, faced with the burdensome expectations raised by its Emmy-winning predecessor, “Breaking Bad.” Adding callbacks from that series and building on its own run, the show delivered a thoughtful contemplation of what transformed the title character, and whether there was any path to redemption.
