If you were a fan of the old Dallas at all, tonight’s new episode of this 2.0 reboot has a sequence that’s not to be missed. J. R. Ewing, played by the late, great Larry Hagman, takes a morning phone call, and who’s on the other end? J. R.’s lifelong nemesis, Cliff Barnes – played, as always, by Ken Kercheval. What a treat.
