Michael C. Hall earned a nomination for Outstanding Performance by a Male Actor in a Drama Series, but I think he's got some stiff competition against Jon Hamm of Mad Men and sentimental favorite Bill Shatner of Boston Legal. Dexter was also acknowledged with a nom for Outstanding Performance by an Ensemble in a Drama Series. However, I would think that one would be a lock for Mad Men.
But I'm glad Dexter is getting this kind of recognition. I also think it's unfortunate that Battlestar Galactica, and Edward James Olmos in particular, were ignored in the same categories.
