The Dexter series finale left a bad taste in the mouth of many viewers when it aired last year. But the hatchet hasn’t been buried yet, because Michael C. Hall is now speaking out about the ending.

“Liked it? I don’t think I even watched it,” he told The Daily Beast in a new interview published over the weekend.

The actor blames the length of the show’s run for why it slipped in quality. “I think the show had lost a certain amount of torque,” he says. “Just inherently because of how long we’d done it, because of the storytelling capital we’d spent, because our writers may have been gassed. Maybe some people wanted a more satisfying — maybe they wanted a happy ending for him, either a happy ending or a more definitive sense of closure. They wanted him to die or something, but I think the fact that he’s sort of exiled in a prison of his own making is, for my money, pretty fitting.”

Hall made the comments while promoting his new film Cold in July in which he plays a different kind of killer. “This guy felt closer to me than Dexter, inasmuch as I would be horrified if I actually shot and killed somebody. I wouldn’t kill somebody then go eat a sandwich after I dismembered them,” he said.

For viewers, the Dexter finale was unsatisfying on a couple of levels. Another big reason fans didn’t like the ending was because they didn’t kill off the lead character. The blame for that particular problem, according to producers, is to be placed on Showtime’s shoulders.

Like any show’s finale, Dexter’s farewell is one that will continue to be debated for a long time.

Does Hall have a point though? Don’t all shows inevitably begin to slide down in quality when they add too many seasons?
