ANiMe ReVIeW: Zero no tsukaima( The Familiar of Zero)

I have seen the three seasons of Zero no tsukaima(the series hasn't finished yet) so it's time tom make a review.
The story starts when Louise La Zero calls (invokes) her familiar when she is in her second year of the magic school
Louise is not a good student and she calls as a familiar a japanese boy called Saito when her friends calls magical creatures. As a result , Saito becomes Louise's familiar. In the beginning she treats Saito like an animal but towards the end of the first season and in the following seasons she falls in love with him.
The plot is about the problems that Louise, Saito and their friends have to fix , there are a lot of them in the series.
In the first season, the most important part of the plot is Albion's war, where Saito and Louise fought. As a result of this conflict they found a plane called "Zero", like the ones that Japanae peopled used to use back in the second world war(this fact is important cause it states that Saito is not the first human who has  ever been  in the magic world). Saito has the oportunity to go back to his world but he ends helping Louise in the war.
In the second season they continue fighting in the war until the end of it. There are some fillers like Colbert-sensei death .
In this season Louise's family is shown and Louise x Saito relationship is developed but they don't openly tell each other their feelings.
In the third season, the last one at the moment , something unexpected happens: there's a new character with a human familiar.
Now that we are here, let's say some interesting things: Saito is one of the main characters of the story and he is very powerfull thanks to his right hand, Gandalfr, God's(kami) right hand , which let him use every weapon of the world. The familar of the new guy has the mind of God which let her controlling magical creatures.
In this season, Louise's friend, Tabitha is kidnaped by her uncle, a new void user like Louise, and she is in a castle. She is saved but the season ends with an ending that lefts a lot of things unanswered. In this season there's a new character called Tiphania, a fairy that saved Saito in the second season.
Louise is not the only girl who is in love with Saito and she has rivals like Tabitha, Siesta and queen Henrietta.
There's a lot of fanservice in the series and it's difficult to find chapters when they centr in the plot

This anime is like a mix between Harry Potter and Narnia's Chronicles(it's probably worse than that).

The animation is something good, specially character's design. The OST is kinda good , the OP's an ED's are good, somthing uncommon nowadays.

There's a lot of characters: Louise and Saito are the main cast , supporting characters as Louise 's family, school friend , queen Henrietta, prince Wales, the villain Jospeh,.....

As a conclusion, I have to say that this anime teach us a bit about Middle Ages: Halkeginia is like Middle Ages Europe.
I'd like to say that it has one of the most amazing scenes I have scene in the seasons two finale.
It's a good anime , but it's not brilliant
