Ostensibly the worst season of Dexter, six didn’t get off to that bad a start. It didn’t really run off the rails until the episode “Nebraska” which inexplicably replaced Dexter’s imaginary father with his imaginary brother and sent him to Nebraska to tie up loose ends regarding the Trinity killer. The season’s whole religious theme, through the introduction of Brother Sam and the Doomsday Killers, wasn’t explored with any depth, and although the apocalyptic tableaus were sufficiently creative, the whole doomsday killer plot became a little tedious. The promotion of Debra Morgan to homicide lieutenant was of course as ridiculous as the rest of that character has been, but I guess her presence is too much a part of the series for that to have changed. Colin Hanks and Edward James Olmos put in fairly decent performances as the DDK (even if I could see the twist coming from the 2nd or 3rd episode). Fortunately, even the worst season of Dexter remains fairly entertaining.
