★★★½ (3½ out of 4)
Jean Smart already has four Emmys, one for each of first four seasons of “Hacks,” the HBO Max series in which she plays Deborah Vance, a standup comic who’d kill for a laugh and show you her scars to prove it. Now, in her fifth and final go at the role that reps her personal best, Smart should prepare for making it 5 out of 5 in the Emmy sweeps. The pain that lies simmering under a joke has rarely been as powerfully conveyed as it is by Smart.
