Story: Well, the story kicks off with a gamer taking over the roll of his character(s) in game. Shortly after being teleported into the game world, he runs across a young, dirty, homeless girl, named Aku. From there, their adventure begins, picking up new characters as part of his crew along the way, although, there wasn't necessarily any real goal in mind, until probably half way through the season.
Art: The art was far from perfect, but not awful, same goes for the animation. The characters did have their distinct traits, but nothing stood out a ton in regards to them.
Sound: Again, I enjoyed the opening for this, it was solid, the rest of the score, was hit or miss. There were certain songs that fit in, and others, that just felt out of place. The voice acting seemed fine, and I didn't have anything that really left me bothered in the department.
Characters: Like I said earlier, the characters were distinct enough to have you remember who they were or what their purpose was, but, there generally speaking, wasn't anything too flashy or crazy about their looks, or character developments.
Enjoyment: I'm possibly being a little harsh with this review, just because, I've SEEN Overlord, and can't help but compare this to it, and it just doesn't hold a candle to Overlord in my mind. I'm convinced, I would have enjoyed this anime more if I had seen it before Overlord, but that wasn't the case. I never found myself excited to watch Maou Sama Retry, as harsh as that sounds, not that it was the only show this season that I felt that way about.
Overall: I give it a 5/10. I think, they took an approach to close to Overlord- and just didn't have the same pizzazz that it did. Like I said, if I had seen it before Overlord, or they had taken a slightly different approach, I might not have been as critical as I am with this one. They did leave the door open for a 2nd season, and, I'll watch that, if they do make it. This anime just didn't do a whole lot for me personally.
