Rimuru himself is the star of the show, this cool slime fella is imensely cool, cute and pretty likeable, he is a good guy, everyone in the anime likes him, everyone watching the anime likes him, he's the kind ideal protagonist a show should have, and most of all, he's original, I mean, when did you see a talking genious magician slime before? I say, never! He being a slime is the main reason everyone likes him, he's jsut original, if he was a simple teenager japanese boy, it wouldn't be the same thing.
Most of the sub-characters are great, we get to know the goblins(which in this anime are good, as opposed to the goblins in a certain other anime), they're carismatic, they're likeable. Same thing can be said about the wolves, tough less carismatic, the leader of the bunch is pretty cool.
Animation-wise this anime is great, I simply love the opening theme's animation, it's really well done, as well as the general animation, nothing feels bad or rushed in it.
OST, except for the great OP theme I don't think there's something really great about it, quite forgetable I must say :/
And that's about it, a more great than good story, a outstanding art, a ok music, a great character and of course I had a outstanding enjoyment.
Overall a great show with imense potential.
