Here's the question:
Modernized dialogue in fantasy - stylistically untrue or clever genre subversion?
I find myself using words like "kiddo", "bullshit" and "badass" in the more comedic side of dialogue/thoughts in my fantasy novel. At first it was simply me not paying attention, and not caring as I knew I'd edit it out in a later draft. But upon reading a little of the writing, I found myself liking the contrast between modern speech and medieval-esque world. In an era of literary subversion, perhaps this is a welcoming addition? Or is this just stylistically untrue to the genre?
Quite simply, is this too opinion-based?
