30 Rock renewed. Three hour comedy block on Thursdays. Parks and Recreation back AFTER The Office (finally!) The Cape instead of The Event for a while. Celebrity Apprentice without Maria and Goldberg but because no one watched non-Celebrity Apprentice. And a bunch of other stuff.
30 Rock at 10 sounds like a major gamble. NBC must be really desperate to get their 10 o'clock audience back.
I was initially very skeptical of Law & Order: Los Angeles. I thought the star power route was a cynical move, but I have to admit that it's worked for me. Alfred Molina and Terrence Howard single-handedly make that show awesome.
Oh, Heroes has been stealing plots and ideas since it's first episode. I mean, the whole concept is essentially just the X-Men from another angle. But they've been stealing, for the most part, good ideas, and implementing them very well.
