As someone not overly fond of anime, I found Rising of the Shield Hero to be a total mess that somehow kept me watching. I'd need a full novel to air my gripes with the show, but I'll try to keep it short.

Starting out as a pretty standard Isekai, the course of the anime is upset by an early misadventure, making our hero pretty unwelcome in the world he was summoned to save.

I've only come to be familiar with the Isekai genre, in which the characters, often Japanese teens, end up in a video game type world with an absurd level of strength relative to the average person, but RotSH fits the mold very well.

From the very beginning, our heroes are barely surprised to be summoned in another world. One has a bow, another a sword, a spear or a shield. "Yeah we've seen that in MMORPGs, move along" they say, despite apparently not being aware of what a tank is. The show goes on a whole story arc insisting on the importance of the lives of NPCs, despite having a literal health bar shown on screen.

The characters are cliche to such an extent it can become amusing, they are completely oblivious to the bad intentions of people around them. Most of the cast is completely one-dimensional, those accompanying our hero in particular have almost no agency and behave in a comically irrational way that sometimes border on deranged. The backstories of the secondary cast come out of nowhere and just serve as confirmation that they strictly conform to the cliche archetype they're meant to represent.

Despite that, and much more (passive protagonist, unengaging story, poorly defined world), the anime does attempt to embark on a more elaborate story than a standard Isekai and depicts more complicated interactions between characters, even if it fails at doing so. If you're just an occasional watcher of anime, I wouldn't recommend Rising of the Shield Hero, but some anime aficionados might be interested in its nonstandard story and dark themes.
