That Time I Was Reincarnated as a Slime is not a bad show, it is very unique for the first 10 or 12 episodes but after that it kind of turns into your typical Isekai. I feel like the characters are the weakest link for the most part, they aren't bad, but there just isn't much depth to most of them. I thought the art and the sounds were very good, but there was nothing stellar. Overall it was fun and enjoyable to watch, I didn't have to make myself watch any of it. But you shouldn't go into this expecting an amazing story, but that'sjust my opinion.
