What’s new on the tube tonight:
Constantine (NBC) Season/Maybe Series Finale: Episode 13 falls on Friday the 13th—coincidence? Tonight’s season finale of Constantine may or may not be the last we’ll see of the DC Comics-based series; rumors abound that NBC cable cousin Syfy my continue the show under its original title of Hellblazer, but they’re still just rumors. So say buh-bye to John, Zed, Chaz and Manny for now, and pray to … whomever … that we’ll meet again on cable.
