Third-person omniscient is out of favor. Do you wonder why?
While we could attribute it to a trend, the best explanation I have is that we’re so conditioned to watching TV and movies, which limit us to the camera’s vantage (third-person limited, if you will), that as readers we expect books to do the same thing.
When I began writing back in the dark ages, I preferred the omniscient voice because third-person limited seemed, well, too limiting. Third-person omniscient was also easier to write because it didn’t restrict me to one point-of-view per scene.
However, those days are gone, and few books published today use omniscient point-of-view. I once heard a podcast recording with Jerry Jenkins, and he said third-person omniscient was “archaic.” That convinced me.
