The first two seasons are on Netflix now, while the current 3rd season is rolling out on The SYFY channel.
The show is about an alien who has crash-landed on Earth, and to blend in, he takes on the identity of a small-town Colorado doctor called Harry Vanderspeigle, all while carrying out a secret mission on Earth. Resident Alien was created by Chris Sheridan and stars Alan Tudyk.
This is a great show, with great quirky characters, and otherworldly shenanigans…
