Disclaimer: I'm relatively unfamiliar with the original Snow Queen story. Do not expect me to attempt to critique this as an adaptation/retelling.
I can see why a guy reading this would rate it highly. It's consistently very funny, and most of the characters feel quite well-realized. It has villain POV right from the start in addition to the main couple - a rarity in this desert of dual POV nothingburgers (sorry, it's rarely done well). Vibes wise it's like if Shrek had kink sex. Unfortunately, in other ways, it's also just not very good. Plenty of the jokes are in poor taste and just sort of unnecessarily mean, there's an unironic use of 'you'd be prettier if you smiled', and the smut is underdescribed but overnarrated. Over-dirty-talked? Whatever. Shit's wack and wasn't very gratifying to me.
But I do understand where they're coming from. I'm very much in the same boat with regards to a little self-pub story called Boundless, by Miranda Sapphire, a story that absolutely *nails* my kinks for being a big, buff woman ogling/pegging a small, beautiful man while being a total garbage fire of editing, plot and (arguably) characterization in much the same way that this is. Because make no mistake, as other reviewers have pointed out, The Snow Queen's editing is abominable, even by the low, low standards of kindle self-publishing. And as funny as they are, every character has a fairly similar internal voice and similar snooty sense of their own intellectual superiority, which gets pretty grating once you notice it. It's meant to be bad when the villain dismisses everyone around them as dull and idiotic, but every POV sort of has similarly conceited thoughts just with a different spin, and like... girl, I get it, I was bullied in school too, but this is excessive don't you think?
Don't go in expecting a consistent tone or setting or anything approaching worldbuilding. It's medieval-ish, but they explicitly have plastic and The Taming of the Shrew, so we're squarely in 'rule of funny' Fantasy Parody territory here, and everyone talks appropriately for that. It can be a little jarring for fantasy parody characters to start having a relatively serious argument about how one of them is kind of unthinkingly misogynistic, but it still falls well within the bounds of the romcom genre imo. It's just, as I said, not especially well crafted beyond the minute-to-minute comedy, but I can see how someone might have a good time with it.
