Black Lightning gives us its Season 1 finale and I’m sure it’ll be troubling and leave us wanting answers in Season 2. Elsewhere, Legion holds our Top Pick of the night because we can’t get enough of this show. Other interesting choices tonight include Shadowhunters (has this show become too focused on Malec?), Rise, NCIS, The Flash and a new docu-series from Nat Geo on the story of the Hitler Youth.
