I don't like rating anything on a scale, I don't feel that you can capture your opinion on a scale of 1-10, but in the spirit of this site I'll try my best, also explaining my reasoning behind those grades.
STORY 3/10
I started watching Fate/stay night with some great expectations, I watched Zero first, so i had some ideas about the story. But unlike the prequel stay night focuses on, for the first half of the series mini harem anime, and then on some cheese romance. I know that Fate/zero got aired six years later, but i didn't expect this much contrast.
In my opinion character building is a crucial part of the story, so there will be in depth review of the characters down below.
ART 7/10
Art ( in my opinion the least important aspect of the anime ) is the best aspect of the show, the only thing they failed to do on this part is that fights were to much flashy energy beams then actual fights. For example last fight between Gilgamesh and Artoria is nothing but beam on beam action, you see some clashes and kicks here and there but nothing more.
SOUND 7/10
Soundtrack was ok, sometimes catchy, but nothing special
Nothing specific about sound, just that there was some weird moments, like Pegasus sounding like a hawk and that sort of minor things.
CHARACTER 2/10
Now this is where the hate train realy starts building some speed.
Characters are poorly built, servants other than archer and saber don't have any soul, lots of side characters disappeared without explanation for a few episodes, villains aren't built at all, they just pop-up.
I couldn't restrain myself from spoilers in this section, if you didn't watch the series you are warned, if you don't want spoilers I can only say that i harbor great hate towards our main protagonist.
SPOILERS!!!!SPOILERS!!!!SPOILERS!!!!SPOILERS!!!!SPOILERS!!!!SPOILERS!!!!SPOILERS!!!!
Shirou Emiya - let's start with our main protagonist, adopted son of Kiritsugu Emiya, the boy that he saved from the tragic fire and raised him as half trained magus (half is maybe an exaggeration).
Shirou somehow gets himself involved in a fight between archer and lancer, somehow gets to escape with his life against an epic hero long enough to get into a shed that Irisviel used as a lab, and with no incantation summons saber, a woman that he instantly falls in love with but doesn't bother to ask her name, ever, and i mean ever, he even says that he will remember being in love with a girl named saber...realy now, girl named saber...
He than dies a few times, gets train by saber for a few days when he realises that he is useless, gets to do to magic that enables him to summon whatever waepon he visualize, and instantly gets adept with that wepon, and his skill doesnt have anything to do with magic, he just has it, wielding swords, daggers and staves like its nothing. And at the end he defeats Kirei in about five minutes, a skilled inquisitor that in last series was able to deflect bullets, move like Flash and at one point chopped a tree with his hands tied around it.
Artoria Pendragon/saber - The thing that buged me was that she didn't tell anything about the last war 'till the point when it was pointless. Here we have new masters, most of them have strong connection to masters in the last war, but Artoria is like nothing to say here...
Rin Toosaka - From the start we see that Rin is well trained mage, but she seems to have some weird ass all mighty gems, ok. Another thing, I knew why she is attached to Sakura, but that is from watching zero first, they didn't explain anything in stay night and their encounters are uneventful until she has to save her. And she gets out of her way to help our useless protagonist.
archer - we don't know who this guy is, but he is a badass
Hercules / berserker - lets just make Hercules roar and shit untill the end.
Sakura Matou - I find some things annoying 'cause i watched Fate/Zero first and i know the backstory, but that only confused me more to be honest.
ENJOYMENT 2/10
Overall it's a weak 4 from me, mostly because i watched Fate/Zero first and i was expecting something along those lines.
