5. Switch Up The Formula
Every season of Dexter so far has played out exactly the same. Dex wrestles with Harry's Code and strikes up a bond with a kindred spirit (someone with similar if not equal darkness), only for that person to turn on him and reveal themselves to be a far worse danger to society than he is.
We're so tired of seeing Dexter's internal struggle over Harry's Code. He either defies it only to realize he made a grave mistake, or he amends it to, say, let a guy like Miguel Prado (Jimmy Smits, from Season Three) in on the game and it turns around and bites him in the ass. How about next season Dexter stays secure about his ritual for a change? We know James Remar isn't going anywhere, so why waste time pretending he is?
