I don't much like the recent trend in manga/anime where the main character is massively overpowered and "battles" are just a way for them to show off. I get bored of it really quickly. A lot of it seems to stem from light novel adaptations but certainly not all of it. The Seven Deadly Sins, for example, would have been so much better if I didn't want the main character to disappear.
With the Slime-chan anime, at least the hot ogre has finally appeared.
I'm hoping the anime for So I'm a Spider, So What? (Kumo desu ga, Nani ka?) follows the manga in that the main character, though overpowered for a lowly spider, gets her ass kicked while she's leveling up and has to run away from top-of-the-food-chain stuff.
