My feelings are split down the middle on this issue.



On one hand the episode we got hint at a lot of future arcs like with Gao, Metal Knight and maybe events with Fubuki.



But on the other hand they had a sappy ending with the Giant pig monster, they already showed up happened to the Mad Doctor and the Armored Gorilla, not to mention the reports that One Punch Man had low ratings due to the audience actually going out to get exercise in Japan.



I love all three forms of OPM whether it be the Web comic, Manga or anime. But let's face facts, this is the age of 12 episode seasons. Unless your a Shonen jump manga. (Jojo, Yuyu, DBZ, Naruto(hell Naruto's anime is gonna last for a damn eternity, and then after eternity...Boruto anime))



P.S. I'm not entirely certain if the OPM manga is classified as Jump.
