I love first person. I think this probably derives from having read some really excellent first-person writing at a formative stage.

The major issue with first person as far as I can tell is that done badly, it's much much more horrible than third person done badly. It's a real challenge to do it well. First person's bad reputation derives I think in part from this unfortunate fact, and also in part because some people just don't like it. Which is fair enough.

People talk about how first person is limiting. I don't see limits; I see challenges. Each to their own.

It is interesting however how first person used to be relatively rare and now it's taking over. To stand out these days you probably need to write in third. Eh, mutato mutandis.
