Resident Alien (SyFy, 10:30pm) — Alan Tudyk (Firefly, Rogue One) is an alien. That might be enough to reel you into this show, but just in case, let’s keep going. Alan plays Harry, an alien who crash-landed on Earth and soon occupies himself as a small-town doctor while secretly plotting to murder humans. That doesn’t go so well, and he ends up helping to solve a local murder, which causes him to re-evaluate his morals within his mission. Yep, this looks like the best kind of ridiculousness and is based upon the Dark Horse comic of the same name.
