Other point before I start is that my review is based only on the anime versions, I never read any of the VN or played the games related to the Fate universe. That being so, let's start.
I have to say that during the time I was watching this I was really hooked to it, I watched it all almost in one go, and I liked so much that I gave it a 9/10 score.
At the time that I'm writing this review it's been some months, and I have to say that now I would lower my score to a 7/10 just because there are moments in the story that are quite forgetful. That's not what you want from a great anime.
The story leads us to a world where everything is set in motion for the Holy Grail War, we have our main character Emiya Shirou, a high school student that is somehow dragged into this world of magic and servants. There are seven masters for seven servants from seven different classes: Saber, Archer, Lancer, Rider, Caster, Assassin and Berserker. Each of the seven masters will fight each other in order to gain the Holy Grail. Shirou, however is the type of selfless person that makes a lot of mistakes and puts himself in danger when there were other ways of dealing with the problems, he want to be the hero of justice and that's great and all, but sometimes he's just stupid. That is what happens in most of S1, Shirou doing everything he can to save everyone, bu putting everyone in danger.
S2 I have to say that I really liked the way it turned out. In this season there is a big twist regarding Archer, that somehow made this into a great show for me. That was a surprise and the one thing i will remember from this show.
I was a great ending and just for that I would recommend it.
The art is just amazing, it's really really good, specially in the fight scenes. The backgrounds are detailed and always add to the feeling of the show. The animation if fluid, the colors are on point, really nothing bad to say here. The fight scenes are just amazing, probably the best ones I've seen in a long time.
The sound is quite good also. The opening of S1 is very good, usually I skip the Op, but I was listening to this one. The Eds are not so memorable, but still in accordance to the show.
The background music was also very good, adding to the feeling of the story.
The characters are the difficult part here, since the most memorable ones are not the main ones. Emiya Shirou and Thonsaka Rin are our main characters, I liked Rin in the beginning, she looked like a strong and independent girl that could handle herself well, but after some interaction with Shirou she starts to feel more like a damsel in distress then what I though.
For me the best characters are Saber and Archer, specially Archer, he really comes a long way, and in the end is the main protagonist in this whole story, at least in my opinion. Saber is Shirou's Servant and she's a bad ass. Like Archer, she's the one that ends up doing everything to save the masters in distress.
The other Servants are also very good, just wished there was more development there. Also from the other masters.
I really enjoyed the show, it's a nice take on good vs evil, and on how to keep sacrificing yourself for other leads to people taking advantage of you. I would recommend Fate/stay nigh Unlimited blade works to fans of this genre, if you like good animated fights and if you like anime that have a ending, as in you feel like it's over.
