The WN is pretty good, as you "hear" more of the main character's POV. It's basically a Monty Python sketch, very funny. JNovel needs to pick it up.
As far as I can tell, either he's completely oblivious of a lot of stuff, or that's what his skill "Dunce" does, makes him not understand things. But don't know, I hear after the end of the first LN (basically the end of the Tanaka arc) it goes off the rails. It's got like 1750+ chapters, though, and the Tanaka stuff is like, chapter 45.
I don't really get everyone's complaints about the story though, as it's an interesting enough take on the genre.
