Classes are back in session, which means all-nighters can no longer coincide with sleeping in until 4 p.m. Here are few new and returning TV series to look forward to while classes get flowing again. New classes and new shows — bring it on, Spring 2011.

Lie To Me

Premiering tonight: “Lie To Me” (Fox), 8 p.m.

In case you missed it: “Episodes” (Showtime), Jan. 9, 9:30 p.m. Series premiere. Matt LeBlanc (sort of) plays himself in this British series about a husband and a wife who want to write a Hollywood remake of their popular British show.
