The delicate polarities that exist within the world of “Shrinking” would certainly include the close-to-antic performance of Jason Segel vs. that of a dryly hilarious Harrison Ford. And the comic dynamic between the glorious Jessica Williams and the askew characters played by Messrs. Ford and Segel. But more essential to the 10-episode series is the seesawing sensation it maintains between profoundly dysfunctional people and feel-good comedy. But the overall sense is a little like laughing at a funeral; the human impulses are familiar, a little perverse and somehow comforting. Ms. Miller is wonderfully droll; Liz’s good deeds do not go unpunished.
