Bored to Death outta be great. The new season of Curb Your Enthusiasm looks good, especially with the Seinfeld "reunion" going on. And I'm really interested to see how David Simon's Treme turns out. It should be The Wire meets The Big Easy. Filming starts down here in November.
As for the current shows, Entourage (as always) is great, even though this season is lacking a bit in action. I like Hung's characters but the writing better take it somewhere fast. Gotta admit, the most entertained I've been on Sundays this summer has been during True Blood's hour. It's a crazy show, and might be hard to follow for those who haven't seen much of this season, but it's a really, really well-written show. Acting is superb as well. Rarely a dull moment.
