Do you have a preference between “person” in the books you read? Do you prefer third-person to first-person? Or don’t you care?
And … why??
Interesting question. I think it depends a lot on what kind of story it is. A consistent first-person narrative means keeping a limited perspective. This can be very effective if it is done right but it requires a certain skill from the author if at the same time he/she wants to convey things to the reader that are meant not to be perceived by the fictional narrator.
On the other hand, there is probably even more danger of careless slipping from an intended main character perspective if the author uses the third-person kind of narrative. I think what irritates me most is when there are sudden illogical side-steps from the main perspective. (Like if 95% of the story is told from the main character’s perspective and we only get a few sudden glimpses here and there from someone else’s unspoken thoughts.)
So I’d say the most important thing is that the author makes consistent and well thought-out use of whatever narrative perspective(s) chosen. Shifting perspective can be totally okay too, but it has to be done in a consistent way or it will come across as “cheating”.
