Most writing is terrible when you think about it. Noone really talks like people do in Media, it's just that we've became used to a certain style of accepted dialog that sounds interesting. When dialog is exellect it really jumps outta the screen at you but that is rare in any media including games. Also, lets not forget that dialog doesn't need to be realistic to be entertaining, I mean christ who really talks like Max Payne? Nobody. But that doesn't make his quips any less funny or his metaphors any less apt.
