Hap and Leonard (10 p.m., Sundance) – If you survived last week’s super intense (and super bloody) episode, you only have to steel your nerves for a bit longer. Tonight’s season finale resolves a few sticky issues, but – unsurprising warning – not everyone makes it out alive. And for those who haven’t watched this series yet (it’s based on the novels of Joe R. Lansdale), you can watch the episodes On Demand. There are only 6 of them, so it’s not a huge time investment. And pay close attention to the very last scene for a clue about a possible Season 2 (please, Sundance).
