Let me sing my praises to UFOTABLE - for managing to perfectly adapt the Fate/Stay Night: Unlimited Blade Works visual novel (VN) into a two-season anime series! The GLORIOUS artwork, animation and soundtracks easily put it among my top 3 favorite anime series in this decade!
My favorite character is Archer: the unique design, the calmness, the no-nonsense attitude, the sarcasm, cynicism, assessments of others, and even "old-man talk" (haha). I love every fight that Archer engages in in this anime. Even though he's not a 5-star Servant in terms of power, he manages to pull win after win against tough opponents by utilizing tactics -- He's a symbol of "trying your best".
I must say, watching Ufotable's adaptation is much more satisfying than reading the VN, because I get to see the most fantastic, epic, eye-pleasing battles that one can ever see in the anime world. I also get to see the characters' movements and interactions - which I can only imagine in my head when reading the VN. I also am extremely pleased to see that Ufotable's adaptation stay faithful to the original VN work! Although all internal monologues are cut out, the anime - through its amazing animation - successfully conveys all the subtleties in the ways the characters interact and fight.
There is no other company that I would entrust this franchise to. I am looking forward to Ufotable's adaption of Fate/Stay Night: Heaven's Feel. I also hope that they will adapt Fate/Hollow Ataraxia soon!
My favorite OST is EMIYA theme ! Absolutely epic!
