SUPERNATURAL
CW, 8:00 p.m. ET
SEASON FINALE: And here’s another series that’s not being recommended, really, but also is being noted for its durability. Supernatural, with tonight’s two-hour episode, concludes Season 12 – and that’s really an astounding achievement, when you consider that the network presenting it, the CW, is only 11 years old. (Nothing paranormal about that fact: Supernatural began on the WB, and was imported to its new home when the WB and UPN merged to form the CW.)
