I really hope there's a season 3. I think there is still so much gold to be mined from the Valerie Cherish's character. especially now that she's an Oscar winner, and Paulie G has been made to look like the fool he is.
I would also like more, but at the same time they really brought it kinda full circle this season and it felt like a great ending. Would have loved a real confrontation with Pauly G, but other then that it was great. I don't know how you could do more without regressing Valerie's character growth from the finale, but who knows? Lisa Kudrow is amazing in this show! :)
There is going to be another take err season. Lisa Kudrow has discussed this in various interviews. We now have proof that Valerie is a good person, but don't expect her to change too much. I wouldn't want her to.
