I don't like it.
I'm not a fan of first person. I find it very limiting, to only know what the narrator knows. I like multiple points of view. I like seeing events that are happening in other parts of the story even if the narrator is nowhere around. I like being inside the heads of other characters and not just see them as flat reflections of the person telling the story. But beyond that, reading "I" all the time takes me out of the story, because I know it's not me doing or saying those things. I'm reading a story about someone else, but reading "I" and "my" and it's jarring. It doesn't work for me and yet it's getting increasingly harder to find books that aren't written this way.
I know there are still good books written in first person, Beautiful Disaster, for one. But they are few and far between. The story has to be really good and the writing has to be impeccable to get me past the narrative.
I guess there are lots of people who disagree with me since first person is so popular, someone must be reading them, and buying them, but it's not me. Seeing "I" is a sure way for me to drop a book without a second glance.
