. ... Also, remember that third Omni is a POV and so it has to be written to the same as any other. It's not just hopping from head to head; it's taking a perspective that can see into all the heads and staying in that.
It's a hard perspective to do well.
Stopping only to reserve the rather obvious comment that
all POVs are hard to do well --
(OTOH, some POVs are easier to do badly than others. For instance, I consider First Person the best POV to write badly in. It is forgiving of many ignorances.) --
I second your thoughtful and insightful post.
My own take would be that selling Omniscient Narrator is not, in and of itself, a problem. Done well, O.N. is deligtful.
And, as someone points out elsewhere, many writers in '3rd limited' slip in and out of an O.N. voice here and there to produce various effects -- introduction, description, backstory. (I'm watching Amanda Cross doing it right now.)
It's more rare for these '3rd limited' writers to take advantage of the great strength of Omni - 'commentary'.
'Emma Lathen' give a paragraph or two of this sort of Omni at the start of their storries.
I'm trying to think of other contemporary writers who are primarily 3rd limited but who dip into Omni for commentary from time to time but haven't had my second cup of coffee and am fuzzy on examples.
But here is Amanda Cross coming quite close -- Lookit here
"Kate's languors, as she realied, were the price of an accomplished life. Or, to put it in a more high-flown way appropriate to Kate's profession, one sank into the ancient sin of anomie when challenges failed."
(where Kate is the POV character.)
This kind of commentary masquerades as deep 3rd POV, but sn actually Omni in sheep's clothing.
This lovely freedom to comment is enticing, isnt it? I still prefer the logical plot organization and compelling emotional depth that come so naturally to with 3rd limited and 1st.
