Killjoys - What2Watch

When this series premiered in 2015, it was a pretty straightforward, action-driven space opera, but starting with Season 2, the cast and writers began building a rich, complex world populated by complicated characters, with an interesting mythology and dialogue that crackles with genuinely witty banter. "Killjoys" goes out at the top of its form tonight with the series finale "Last Dance," in which Dutch (Hannah John-Kamen) uses Khlyen (Rob Stewart) to bait The Lady, initiating a final showdown. Aaron Ashmore and Luke Macfarlane also star.
