I do not like the religious overtone that appears to be a huge part of this season, but that's really the only thing I didn't like about this episode. This episode set the tone for the year, and I really liked it, despite the fact that not a lot happened. You had the good mystery as to whether Mos Def's character is really good or bad, and you had a nice fight scene and staredown, albeit one oddly short. I think I laughed at Deb's lines tonight more than I have maybe ever.
This is Dexter at its best. Strong writing, strong acting, nice mystery.
