I'd rate this story wise as a 6/10. It's generic as hell average isekai anime. HOWEVER I rate this "personally enjoyed it" as an 8/10. The pacing was good, and the slimes MADE this for me. They were hilarious and the rest was just there to keep you entertained. The animation was solid enough, the score was great, the opening and ending themes were fine, in fact loved the ending one. And the post-credit "preview" was exceptionally amusing to watch also. I won't say "go watch this" but if you're looking for some fun time-filler, and don't want to get bogged down insomething heavy, this is probably a good option for you. However if you miss it, you're not going to regret it.
