Dexter - Miami's most likable serial killer?

I watched the first 2 episodes of this new Showtime series on the Showtime website tonight. Michael C. Hall is fantastic, and plays a character far removed from the undertaker he played on Six Feet Under.

Dexter works as a forensic blood analyst for the Miami PD; his sister is a cop, as was their foster father. Dad realized when Dexter was young that he was a psychopath, and channeled his pathology towards killing those who deserve it - a serial killer preying on young boys, a rapist/snuff film killer, cop killers . . . . Dexter floats through life; he realizes that he is incapable of normal, human emotions, so he fakes it.

While I realize that my determination to tune in regularly for any new show has been the kiss of death (sorry Smith and Kidnapped), I'm going to check Dexter out again.
