The Dexter series finale enraged many fans for many reasons; chief among them was the fact that Dexter lived — and became a logger? — despite having driven his boat into a hurricane. “How about that finale?†said Dexter producer John Goldwyn at the NYFF premiere of The Secret Life of Walter Mitty this weekend, when we asked how the writers decided on that ending. “They won’t let us kill him,†he told us. “Showtime was very clear about that. When we told them the arc for the last season, they just said, ‘Just to be clear, he’s going to live.’ There were a lot of endings discussed because it was a very interesting problem to solve, to bring it to a close. People have a relationship with Dexter, even if it doesn’t have the size and the ferocity of the fan base for Breaking Bad. But it has a very core loyal following.†Yes, and a mostly disappointed one.
