An uneven season - combination of continued strengths and serious misjudgments. As ever, Michael C. Hall holds everything together - his Dexter determined to be a good father, killing of villains never clashing with little Harrison's bedtime stories (where a hero despatches monsters).
The series again interestingly evolves. Dexter stands at the crossroads, torn between light and darkness (well acted reformed gangster Brother Sam prompting a rethink). Also with impact is Debra's promotion to Lieutenant, she feeling increasingly isolated - her therapist kept busy.
The great flaw concerns the dominating Doomsday storyline, source of spectacularly gory deaths. The theme itself has possibilities, but not as presented here with loopholes abounding. Not for a moment does the Gellar-Travis relationship convince, especially after the Ep.9 bombshell where everything becomes ludicrous. An embarrassingly miscast Colin Hanks as Travis lacks any hint of the inner torment, driving mania, essential for the role.
Amongst other concerns? No mention of Dexter's two step-children. Quinn in freefall, now increasingly a boring waste of space. Lazy plotting - some escapes of the "with one bound he was free" gene (as with that blazing boat), people turning up out of the blue (as with that otherwise brilliant season cliffhanger).
12 episodes. Modest extras, of them cast interviews the most interesting.
Most series inevitably sometimes wobble a bit, emerging the stronger with lessons learned. With plausible storylines and more carefully chosen guest stars, there is plenty of life left in Dexter - although, hopefully, not in some of the people he targets.
