Without the great Allison Tolman as a stabilizing and unifying presence, “Leslie,”Mad Dogs’ sixth installment, resumes its previously very, very heavily serialized model. As I’ve said before, the show’s episodes increasingly feel less like cohesive (if to-be-continued) units and more like fifty-plus minutes torn off at random from a ten-hour reel. Think of how different the first half of this ep, with its Outbreak/Contagion quarantine claustrophobia and paranoia, feels from the second, with Joel and Cobi cutting and running and communing with beatific locals and tourists they encounter along the way. You could have rolled the closing credits right in the middle and begun an entirely new episode for all their stylistic and thematic continuity.
