I don't know where to start for this, to sum it in short words,its extremely boring, the guy is reincarnated in the world of Tanaka is always listless or something like that with a mash of other anime worlds like daily life of highschool boys and so on. So here are my problem with this story
1) Why does he act the same way as Tanaka,isn't he a reincarnated person,if you are going to have him act the same way then why bother making him a reincarnated person? Just so he can know all the other anime characters ? But even so if he knows them he won't bother interacting with them because he is lazy so what's even the point of it.
2) The dimensional chat group function feels entirely useless, up until where I have read it, it serves no real purpose then letting the members know that they are a part of an anime.
3) Its extremely boring to read,its not like each chapter is big or something but that's not the problem,the problem is that the chapters are short and boring. I don't even want to read further than I have already just because of how boring it is to read
4) One of the tags is action but there has been none the first 15 chapters and by the looks of it, there won't be many action scenes so I would put slice of life as a tag rather than action because I think the novel is more oriented towards that.
So final though , its extremely boring.
