The season 6 premiere of Dexter was Showtime's best opener for 14 years, with an impressive total of 2.8m viewers. At the same time, negotiations over Dexter's future reached a stalemate between the network and its #1 show's lead, Michael C. Hall. The actor's representatives are asking for a two-season deal with $24m, but Showtime are only prepared to pay $20m.
I'm sure this matter will be resolved quickly (what's $4m in the big scheme of things?)s, so fans shouldn't worry. However, in light of what we've been discussing in the comments below my review recently, I'm not sure I'd be happy to see a seventh and eighth season... with even more likely if ratings stay healthy and Hall's agent can afford to play hardball. Seeing as Dexter doesn't have a "mastermind" (like Mad Men's Matthew Weiner) who's the driving force behind the show's success, it feels like the only thing that'll kill Dexter is a catastrophic drop in popularity, or Hall getting so bored he'd even turn down $24m offers.
