Q is equal parts entertaining and annoying. He is responsible for some great star trek episodes ("Q Who", "Tapestry") and some not so great ones.
Trying to analyze the Q is nonsensical. It's like trying to understand humans from how we act in video games.
Always nice to see John DeLancie show up in other series like The West Wing, Stargate, and Breaking Bad.
