DON'T MISS: "Episodes" – As the hilarious Hollywood satire launches its fifth and final season, Sean (Stephen Mangan), Beverly (Tamsin Greig) and Matt (Matt LeBlanc) have all pretty much hit rock bottom. The latter – playing a twisted version of himself – is now the host of a ridiculous game show called "The Box." And even though it's a huge hit, he's worried that the gig will damage his acting career. Sounds like a man without a plan. 10 p.m. Sunday, Showtime.
