Or as it was called, Tensei Shitara Slime Datta Ken. It was a solid production, but in the same time a disappointment for manga readers. There was seemingly no dramatic tension, even in major fights. I think the only time I was interested in the story was when our slime had to fight Milim, who clearly was unbeatable (by the time I watched the anime, I forgot how the fight went down in the manga).
Liked: It was allright
P.S. Now I'm worried for an anime adaptation of Tensei Shitara Ken deshita. I actually re-read it once in a while. On the other hand, a poor adaptation does not take the manga away from the readers. It only robs the watchers and incurs opportunity costs on the studios.
