Hung blows. While the idea is good, and the new girlfriend is fine, the show sucks. Its like they said, "Hey lets find the two ugliest kids trying out for the part, put them in the show, and then have them serve absolutely no purpose besides looking like chemistry experiments gone horribly wrong."
Then they casted Tonya's part and said, "Lets find the most unattractive, homely looking woman to play the show's second most important part and make her obnoxious and whiny. That way we can make being a high-end, madame as un-sexy as possible."
Obviously HBO is trying to play on the success of Weeds from Showtime, but Hung is just plain terrible.
