Nurse Jackie 9 p.m., Showtime 2
Do not read this if you haven’t seen the season finale yet. But if you did see it, what did you make of Jackie’s decision to pop a pill on the occasion of her first sober anniversary? It felt contrived to me at first, as if the writers did that simply because they needed to set up next season. If Jackie remained clean, the future of the show might seem pointless. But then, it is true to the character, that she would once again ruin something good. From the minute we met Jackie, we saw her taking apart her wonderful life for no reason. Her self-destructive instinct is a beast.

This new reality series is about a Midwestern family named the Cutters who run an oil company. Black gold, Ohio tea.

Discovery is promoting the show as a David vs. Goliath struggle.
