I have no yet experienced it, but I think it's OK because the main characters is/are supposed to be sortof a blank state in most RPGs. It's the companions that usually have their personality and reactions fixed and unique.
Straight-to-the-point generic dialogue for the main (you) is OK in my book, it's very similar to how many heroes from books are actually bland when the reader is supposed to identify with them.
That's just theorical from my PoV, perhaps I'm missing something.
