MIDSEASON RETURN: This very entertaining sitcom returns with the first new episode of 2016, and it provides an interesting twist: One of the brothers is jealous, but this time the jealous sibling is Rob Lowe’s Dean, not Fred Savage’s Stewart. It’s partly because a newspaper reporter is coming to town to write a profile of Stewart – but it’s also because one of Dean’s former Hollywood “friends,” Timothy Olyphant (in a recurring role as himself), is stealing not only his thunder, but perhaps the interest of available women. The episode’s title? “The Olyphant in the Room.”
