Maybe it sounds a little stupid, but my question is: why deep point of view is better than omniscient point of view? In school we don't even learn about the former.
It's not that I don't like it, I love it actually (deep point of view I mean) but I would like to know what is it that makes it better than omniscient.
I answered in the comments section, but then thought that other writers might also be interested in the answer:
It's not a stupid question!
Deep point of view inserts the reader into the character's body, which often creates a more deeply emotional reading experience and consequently makes the book a bit richer emotionally. Epics told in omniscient point of view tend to be very sweeping in scope but sometimes a little shallow in terms of emotion.
Most readers don't realize that the publishing industry has moved more toward deep point of view rather than omniscient in the last several years. It's an industry trend. Most new writers wanting to break in to the industry now should probably write in deep point of view if only to increase their chances of being contracted.
When I mention how the industry has moved toward deep point of view--I promise I'm not talking out of my butt. I have spoken with numerous industry professionals--editors, agents--as well as worked personally with several publishing house editors. They all agree that deep point of view tends to be preferred in the publishing industry today when they look at manuscripts from unpublished writers.
Multipublished authors will sometimes write in omniscient point of view. However, that is because they are multipublished and have been in the publishing industry for a long time. They can pretty much write whatever they want. You will not often see debut novelists writing in omniscient point of view for an entire novel, although there are exceptions, naturally.
However, for most of the unpublished writers whom I mentor, and for whom I critique, I usually suggest they switch their manuscript to deep point of view to increase their chances of getting contracted by a traditional publishing house.
The one glaring exception to everything I've said above is literary fiction. My experience is in genre fiction, not literary fiction. So I haven't talked to any editors who specialize in literary fiction. They might say that omniscient point of view is preferred for literary fiction, but I wouldn't know.
