Complex co-sign: After last season’s gut-punch finale, in which the Trinity Killer murders Dexter's wife, we had some concern that the show wouldn’t be able to top that in season five. Our fears proved foolish, though. Freeing Dexter up from the old ball and chain and step-kids so he could focus on juggling just his biological son, other murderers in need of extermination, and Lumen (Stiles), a rape victim he unknowingly saves from death and helps get revenge, and his sister, who is closer to his homicidal secret than she knows, gave the show new life. No small feat for a show about savagely murdering people.
