The worst part of this anime is the overarching bigger picture plot that is never discussed and hardly ever reaches any conclusions. Of course that is the fact that the mc is stuck in a video game and never answers any of the questions to why he is trapped in that world and what will he do about it to figure out how it happened. Only head canon theories can the fans lean towards but this show should bring some closure to this point that he might never get out of this matrix. They are milking it dry of Ainz taking over the lands and becoming a ruler but nothing about his "real life" origins or a need to return back. Sword Art Online literally did it in 12 episodes and us the viewers knew exactly what was going on with all those people being stuck inside the virtual environment. No investment mystery box that makes you want to keep watching. It doesn't matter, things just happen and we are supposed to feel engaged to know more about it. It isn't a slice of life. Not enough cliffhangers of intensity to generate conversation.
