I’ve asked myself this question and answered a resounding no. A writer should have a consistent style. But, if I compare my review of 28 Days Later, written in 2003, to my review of 28 Weeks Later, written four years later, I am resigned to the fact that they have different styles. This is really disconcerting to me, as it shows a flaw. All I can think of, is that a writer may use different styles of writing for a while, then settle on one style. This style becomes natural. In the end, a writer or some, if not many, writers must go through this phase. It’s a natural part of the writing life. One must write to know how one wants to write–and sometimes if not many times this plays out in the publishing world.
