_--{Short and sweet reviews for the average anime fan!}--_
If I had anything to say about this series it would be that it was good.
Not exceptional, not great, just good.
I give it a score of "something I'd watch while eating/something I would stay up all night watching"
Though there are some good things to say about Maou no Yuusha. It has great animation (BOOOOOOBS) and changes things up a bit by putting a large focus on... economics and learning. If you love Spice and Wolf like I do, you'll find something to like here. OH THE JOYS OF ECONOMIC EXPLOITATION DURING TIMES OF WAR.
As for the cast.... how could I forget such characters such as the Hero, the Demon King, or even female knight... no, I did not forget their names that is really what they go by in the show. No one actually has a "name" in this story. There's romance in here among characters but nowhere near enough to bring a tear to your eye. A "That's a nice moment" at most.
I can't really see much of an improvement in a 2nd season unless the story really diverges from how it flows now. If you're really interested in this series I would suggest reading the light novel instead. Scenes and moments have a little more impact when there isn't a time constraint. Imo I found it to be much better.
