HIS DARK MATERIALS
HBO, 9:00 p.m. ET
SEASON FINALE: This series ends its first season with an episode that, as much as any other this year, pulls the rug out from under the viewer by refining a major character’s background and motivation. James McAvoy’s Lord Asriel is one of the characters to keep an eye on… but surprises, in this Season 1 finale, come from many directions, so grin and bear it. (Bear. See what I did there?)
