It's fine for there to be a POV character. It's an established storytelling methodology. If people don't like Dr Samadi, that's less your fuck-up than theirs. And yeah, you seem to be giving your characters room to grow, which I like--this is an ensemble, right? That's sort of the idea.

Urrrgh, I mean--just let things be what they damn well are, or disengage, you know? It's not that hard. There's more than enough stories to go 'round.
