Most Underrated Anime?

There's a lot of anime people love and many of which are seen as the most popular anime worldwide, but I'm curious as to what you guys believe to be the most underrated anime which may be your favorite or one you think simply deserves more appreciation. Mine are K-Project and Black Lagoon

Black lagoon is a good one. For me, while not necessarily underrated, Erased was a show that was immensely popular at its release but kinda got forgotten a few months after it's season. Erased is easily one of my favorite anime if not my all time favorite anime.

Hundred is very underrated but is my favorite anime.

Off the top of my sleepy head, I'd say either Sunday without God or Severing Crime Edge. https://78.media.tumblr.com/faaa4c3f3cc5915dd3c1bfa4c1e80b70/tumblr_njl0ovL1kC1rydwbvo1_500.gif Sunday Without God was just a really nice gem I bought without much knowledge other that seeing like one scene. https://78.media.tumblr.com/abe65145b75025c973cfb9b51a5dcf38/tumblr_nubctzKYp71sprzgyo1_500.gif Severing Crime Edge was interesting to say the least. It has some weirdness in that it might as well be Hair fetish the anime. Ignoring the intense hair petting and touching, the rest of the anime an action/romance where the mc has to protecc main girl. Both suffer from the issue of, they really need a second season. Both animes are hella unfinished in their story and neither light novel will probably make it over here anytime soon if at all.

"Colorful" is an anime movie and it's not well known, maybe because of it's 'not so good' stylization of the characters but the plot is great.. I recommend it for people who have depression and wants to commit suicide like me. It made me cry so bad.

Katanagatari Saiki kusuo no psi nan Mawaru Penguindrum Princess Tutu and Yuki yuna wa yusha de aru Man, those anime are so underrated
