Maid-chan didn't say something was especially wrong (except the statuesque expression), but the anime has to live up to the games - and that he does not.

Also, stand alone, it is has no special points at all, if you don't see catgirls in maid uniforms as special.
It also shows the budget constraints. Maid-chan is quite sure the backgrounds are taken from the game. But that, in turn, means that the backgrounds look bad compared to the high quality, detailed cats graphics.

All in all the anime is a bland piece of work without spices. You can fill your belly, but you won't remember your meal.
