Moe animes gonna ruin the anime industry, I hear a lot of this in this last years, but I still expect that the "moe" wave is just a tendency to attract consumers and that don't matter to make a anime good or bad. Blend S it's a example of that, the anime have a lot of "moe" and "ecchi" but that doesn't affect the anime at all.
The plot is pretty simple, but it's a recipe that worked in the past with another anime, to be honest, it's a mixtape of all we already had seen in another animes about a job. I like a lot of the art and the characters design, the soundtrack suits very well the setting of the anime and the animation is seemly to a comedy.
Isn't the kind of story that gonna change your live, don't gonna give you a new philosophy, but is good to give a enjoyment, have a kinda of comedy, a kinda of romance and do what he tries to do (comedy sense is your criteria).
It's a 8 (7.8).
