Basically, it's an anime set in a RPG like world with levels and skills and all those geeky terminology that only a handful of people will know. I will give props to the show on it's aesthetics, but comparing the look to the actual content is pretty unfair the way I see it. I say this because honestly, nothing really major happens in the show and each episode feels more like it's own stand alone thing than a chronological series of events.
Nothing issue I had with the anime was the jokes that was kinda it's main selling point. Not saying the jokes were bad, but they did start to get repetitive after sometime making it obvious where the plot of any particular episode was going. This happens because the characters are basically one trick ponies when it comes to personality where at some points I actually forgot their names and actually knew them as "Protagonist", "Useless Goddess", "explosive Witch", and "Masochistic Knight".
I feel like the show does a good job with their comedy, which I won't say is a bad thing, but it kinda just introduces you to a character, shows you their quirks, and have you laugh at them without anything new being added to the character. Sure there may be a conflict or two they face, but by the end of the episode it's almost like it never existed and come next episode it's almost like it completely forgotten that it ever happened.
I can't really fault the show on what it is, because I will admit it's entertaining, but it's nothing I think should be praised as a masterpiece for what it is. Basically, watch it if you want a good laugh, not a good story.
