@Terrence Albedo is my phone wallpaper haha. I can understand how Overlord wouldn't be to some peoples taste. Overlord is a really deep read, with what could be considered long periods of uneventful circumstances if you don't connect the dots (which I often don't because I gloss over things).
What is truly extraordinary about Overlord's writing is how intelligent the world and characters are, how the books convey their sense of scale, fear, awe, and sometimes just write an amusing silly moment. There's a lot of text to sift through, which is uncharacteristic of the general light novel scene. Overlord takes immense pains to craft a world beyond the character, to take those characters and let them truly exist in the world its created, they all have motivations, fears, likes, dislikes, and sometimes, exist without definite purpose, because that's what life is.
To me, Overlord is a window into something familiar, yet something totally unlike anything I'll ever experience, a grand stage to play out the dull intricacies of humanity with circumstances taken to the extraordinary. Most light novels are fluff like this one, where the world and it's characters exist to be shaped by the protagonist, to be experienced by the reader at face value. It's exceptional light novels like The Faraway Paladin, Overlord, and Grimgar that transcend the superficial experience. That being said, fluffy reads can be fun too sometimes! I'm reading Smartphone and I hope it doesn't get any more Harem-ie than it currently is.
