Overselling can hurt a show... it got so much hype before it came out, that if it failed to live up to it, or the writers took the show in some unpopular direction after it could get less than pleasing ratings... I personally don't watch anything unless it's recorded the night before or already on dvd. I hate [most] commercials.
Loved the first couple of seasons. Last 2 were kind of boring, but I'll keep watching. It seems to happen with a lot of great shows. They're written for one season, and are granted more, and the closed story gets an extension that isn't all that natural. By the 4th season, it seems to lose the plot.
Yea I agree the first two seasons were modern masterpieces in my book! I even own them on dvd. season 3 was nothing but good acting, no good story lines that lived up to one or two. I havent finished season four yet but this is still one of my fave. shows!
