Critic’s Corner: What’s on TV this weekend

Randy Tepper/Showtime

Dexter Sunday at 9 p.m., Showtime

While the energetic “Ray Donovan” starts its life at 10 p.m., the played-out “Dexter” returns at 9 for its final season. The show picks up about six months after Deb shot LaGuerta to protect her brother, and she is not very happy with herself. Shame spiral alert. Meanwhile, a new psycho is on the loose in Miami, scooping out brains, and Charlotte Rampling (above, with Michael C. Hall) shows up as a therapist.

Friends marathon 8 p.m.-midnight, TV Land


You can already watch it on Nick at Nite and TBS. But for some of you, that’s not enough – you know who you are. As of this month, TV Land is also airing repeats of the sitcom all over the place, including this little marathon. Why did TV Land bother? Because these old episodes still bring in lots of viewers. Maybe NBC should consider rerunning them in primetime (kidding).
