Housing in Los Angeles can be expensive, which is why it’s not uncommon to find 30-somethings who still live with roommates. “Dwelling” is a comedy about the lives of three such roomies created by Anthony Q. Farrell, a writer from NBC’s “The Office.” Though the web has been saturated with comedies over the past year, this series stands out with quality writing and well-defined characters. I found myself hunting for the “next episode” button after each viewing.
