Story:
The story for this show is mediocre at best and completely nonsensical but that is part of the fun. The plot is not deep and even when the show seems to be getting serious it is just setting itself up for more gags. But it does have at least a few serious moments especially between Mahiro and Nyaruko.
Characters:
This is the driving force of this series. The plot is just an excuse to get the characters in situations but it is what the characters do within these situations that make the show fun. You never really know if they are going to parody another show, do their own thing, or actually act serious for a bit.
Sound:
Personally I loved the opening song. But besides that some of the in show music (like whenever the world shifts red) are fairly good although not really anything original.
Overall:
This show is not serious but it was not meant to be. Personally I had a lot of fun watching it and I'm sad that it has ended.
