This season starts with plot right off the bat and never stops. What I mean by this is that, unlike previous seasons, there aren't episodes that feel like "fillers". The art is top notch, specially during action sequences and the sound quality is solid. Overall, it's a good season but there were a few things that left me upset. However they are SPOILERS!!! 1) At some point in the show, Luvia gets her outfit ripped to shreds and basically she goes topless for ages. The way that this is animated makes it impossible for her to have nipples and this really triggers me. Fair enough ifyou want to show cleavage and give some fanservice but make it anatomically plausible.
2) In the Parallel World, we get an older Emiya Shirou. Same full name. Brother of Miyu. Why use the same exact character? Why is he the only one that has a version of himself in this World?
3) The show ends on a very annoying cliffhanger, without any reference to any future release, and they better answer a lot of questions (including the ones above) through the movies.

All things considered, it's a 7/10 from me.
