Ready to get up close and personal with a serial killer? Showtime has released a new trailer for season 6 of Dexter, and it’s engaging, entrancing, and quietly disturbing. “I’m feeling like my old self again,” intones Michael C. Hall’s Dexter, sounding like the confident killing machine from earlier seasons. Season 6, which debuts this fall, includes guest stars such as Edward James Olmos, Colin Hanks, and Mos Def. Watch the clip below.
