That Time I Got Reincarnated as a Slime Review, Empire-Building at a Walking Pace
A reincarnated slime skips the revenge arc and founds a nation instead, in 2018's most agreeable isekai.

The rare power fantasy that spends its power on infrastructure, comforting, clever, and light on real danger.

The strangest thing about this show is how relaxing it is. That Time I Got Reincarnated as a Slime opens on the genre's stock death-and-rebirth beat, then immediately swerves: instead of grinding for revenge or glory, its protagonist, reborn as a blob with an appetite for absorbing abilities, starts solving other people's problems. A pack of goblins needs protection. Monsters need a town. Neighbors need treaties. The 2018 series, 24 episodes of TV, is less a battle shonen than a municipal project with fight scenes.
From a pacing standpoint, that's a bold trade. The show's momentum comes not from tournament ladders but from accumulation. Each episode adds a species, a craft, an alliance, and you can feel the settlement compounding like interest. When fights do arrive they're brisk and readable, staged to establish new relationships rather than to bruise. Rimuru's skill-absorption gimmick keeps the action inventive, and the ensemble of monster lieutenants gives the comedy a deep bench.
The honest caveat follows directly from the premise: the protagonist is so capable, and the world so eager to be won over, that genuine tension is scarce, problems tend to dissolve on contact rather than get solved under pressure. If you need stakes, this will feel like a warm bath. But as comfort-food worldbuilding executed with real craft, it's top of class. Three episodes stream free on AnimeSphere; the settlement-founding stretch will tell you everything.
