Resident Alien wraps its four-season run with a beautifully heartfelt series finale that gives every character a meaningful sendoff.

One of the best sci-fi shows of the past decade has left our orbit in a series finale that was as full of heart, hope, and humor as it has been since Patience, Colorado’s Dr. Harry Vanderspeigle was first taken over by a Law & Order -loving alien with an unpronounceable name (the Emmy -robbed Alan Tudyk ).
