-First of all, despite all what fans say about novels, what you get on screen is what is important for an anime; and what you get on screen is what you would get if you put Hadji from Blood+ in a high school & magic series. The MC is an emotionless guardian of a High School girl, but what you see in the series is that he is more focused in helping in club activities than guarding this girl. This overpowered emotionless sis-con main character ends up involved in some "High-school police club" and in a "science project" in the last arc, only to show he is super cool minded and intelligent and strong. But if he has no feelings why he participates in activities that feed ego, and if he is so intelligent how the convince him??
The only girl that doesn't fall for him, is just used for a scene where they say something like this : "You like Tatsuya but as he is super power full and cool and you are just mediocre you choose a mediocre boy, because you will never be as godlike like him"
-Second, they over explain everything. When they cast a spell they explain all the steps and the names and the calculations,etc. It is not intelligent, it fills empty spaces with senseless blah blah blah...
Conclusion: As the anime is 100% the main character and the main character is inconsistent and empty (ON SCREEN) and isn't enough interesting (At least without the novels information) , the show is quite monotone and repetitive.
(Story 2 + Art 6 + Sound 5 + Character 1 + Enjoyment 1)/5 = 3
