Featuring the Deftones. In the past few seasons, Dexter has lost the quality level that defined it and made the early years so much fun to watch. But there's hope yet for season seven. For one, the plot is likely to be more interesting because SPOILER we'll see how Dexter reacts now that Deb is on to him and his secret life. Secondly, they used the Deftones in the trailer. That deserves our watching the first three episodes at least. They've earned that much.
