If you’re a fan of the TV series Firefly and its sequel movie Serenity, today is an excellent day to rewatch them—April 24 is International Watch Firefly Day! (And if you’re not a fan, you’ve obviously never seen it, and you should remedy that moral defect immediately.) Firefly—basically a western set in space (complete with cattle!)—is among my favorite shows of all time, and though it was tragically short-lived, its spirit endures. Keep flying.
