the art is hit. mangaka has no clue how to portray movement for an example. the style doesn't suit the story at all. the aliens look retarded.
the whole concept of the manga is a ripoff. poorly done uninnovative ripoff, that is.
the setting of the story is blatantly stupid and unrealistic. characters are unrealistical and simplistic with idiotic motives. the plot goes nowhere and is heavily repetive and predictable.
but hey! it has the hilarious penishand scene in chapter 1.
