Work in process, same as with other media topics. I have not viewed a ton of animes, but seen many with 250+ eps. Hoping for user contribution since many watch anime or read manga and may have some great ones to share.

-I intend to find a image or two later on to include to make the page come more alive and fun. This requires snapshotting images, resizing them and uploading them for anchoring into the post as just using the image from random sites results in the links becoming invalid eventually.

Format will be as follows:
"Name of Anime or Manga" with clickable link that takes you to anime planet where it has a outline of the anime.
"Link to one site" for your convenience. 

Anime:

Gintama
Link to all episodes.
Rating 10/10. Gintama is the best anime I have seen and just plain funny. The characters are quite unique and entertaining. There is not much story to this anime, but more randomly funny with a ton of spoofs of things like DBZ, Saw, Nintendo etc.

Higurashi no Naku Koro ni
Link to all episodes.
2nd Season: Higurashi no Naku Koro ni Kai , Link to eps.
Rating 8.5/10. This anime gets a little complicated. The main idea here is that it is a repeating story of the same time line, and the episodes are shown from multiple perspectives or with changing events on each reoccurance. It is somewhat cute but also evil and funny.

Manga:
