List of completed and ongoing manga and light novels that are licensed in English (it can cover US and UK).
The Manga series that were... un-impressive to say the least. Every item on this list has a rating of less than 2 stars. (In my opinion, no one get upset about it. I'm sure there is manga out there that I love and you hate.)
Completed Manga I can read.
I have seen related Anime or read related Manga.
Make sure to check if there is any more Anime or Manga related I need to watch/read.
