Not your usual sit-com. I really don't know how to describe this show. On the one hand it's a situation comedy, with a rather odd set-up. On the other it has no laugh track, apart from a few main people the cast keeps changing, and the main character is most likely seriously agoraphobic.
Don McKellar plays Curtis, who is antisocial to the point of never leaving his apartment. And I do mean never. Roommates come and go, he just stays home and watches TV. It sounds terribly dull, but the show is shockingly addictive. It's not for everyone, but if you see one episode you won't want to miss the rest.
