Basically,we already have a review section,however,can we add a review section for anime,manga and cartoons?As there are many anime lover and manga lover,don't forget cartoons lover. If it's possible to have a review section for Anime,Manga & Cartoons section, I suggest it'll divided into two,Anime & Cartoons,Manga & Comics.
There are a lot of unfinished anime and mangas out there, not a good idea. And refer to tehuber1337's post, kinda forgot about crazytuna's.
Yes,that is also a concern.Finish or not,if a manga or an anime is 12 or more episodes/series long,you mae a review base on the storyline so far. Oh,sorry,I forgot to use the search feature.
