Starts off pretty well, then the pop culture references start seeping in but the MC is a transmigrator and clearly one of us because videogame, film, anime, etc, references are pretty much all he brought with him to his new world. But then... then the pop culture references start worming their way into the world background and lore. From details remarkably similar to other web novels to plot points pulled from HBO shows, and the names that get used. Well, to put it plainly this now seems less like a transmigrator story and more like the story of a culture junkie who got hit by a truck and we're now reading his coma dream. I guess its personal preference, but when MC makes a Witcher reference because he played the game, I'm cool with that. But when Ice Queen Elsa's kingdom is dealing with an invasion of White Walkers in the North, that's too much to treat seriously.
