Just as the novel, a boring, dull, repetitive and unfunny mess of anticlimatic encounters one after the other with fresh out of the template factory villain that all amount to nothing because they all die before they get any kind of relevance while the author is trying to shoddily cram everything he can think of from every genre (isekai with a OP MC, dragons, robots, explosions, magic users, mind controlled female slaves, big boobed classmates, ancient warrior clans, ghost, isekaied asshole classemates, zombies, vampires, tower death match, sword saint, devil, monsters, secret governement factory, scientific mysticism, evil magic rulers, a whole lot of people dying for nothing over and over again just to make the situation look dangerous, etc...).
Basically it's like reading a story where the author skip or fast foward 2 or 3 pages for each one he wrote.
