Story (7/10)
The show is set in Fyuuki City where the 5th Holy Grail War happened. 7 masters are randomly picked and they summon a "servants". Servants are heroic spirits summoned to serve the master. 7 masters and 7 servants fight together to claim the ownership of the Holy Grail which can grant any wish you want.
Fate/stay night is based on a visual novel game where the player must decide how the story will go. Fate has 3 paths. The 1st path is Fate, the 2nd path is Unlimited Blade Works and the 3rd path is Heaven's feel. This show is primarily focused on the first path. These 3 paths are 3 different realities. How can I explain this? It's like 3 alternate universe.
The story starts slow showing Shiro on a pit of fire being rescued by Kiritsugu Emiya. From there on, the story advances slowly to introduce some main characters and later picks up.
In my opinion, the story was pretty decent. It was great at the first half and early 2nd half but started to lose its focus later on. The story pacing is slow in this show so you can actually understand what's going on. There was also some plot twists in the show but I wasn't shocked when I saw the plot twists because I made a grave mistake of watching Fate/Zero first. The ending of the show was meh. Some people say it's confusing at what happened to "that" servant but I didn't find it confusing. Btw, I'm not going to spoil the ending.
Art/Animation (5/10)
The animation is mediocre. It was like some smart-ass 5th grader doodled on the environment and the characters. There was no shadows, no details and the environment looked bland. The character design was decent but could have been better. Wait? What am I talking about? The show was made in 2005, of course the animation is going to look crap.
Sound (5/10)
The soundtrack wasn't really that great. There was 1 or 2 battle themes that gave me a light goosebumps but overall, it's just utter crap. Now, the opening soundtrack. The OP 1 was complete trash and should not be even listened to. After 3 episodes, I started skipping the opening because I couldn't bare listening to it again. On the other hand, OP 2 is a huge improvement from OP 1 but it's still not a great OP soundtrack. Now, the ending soundtrack. Only 1 ending song was used for the whole season and it wasn't that great either.
Character (7/10)
Since the show has slow-story pacing, they took time to introduce the characters and give them some character development. Some of the characters in the show were likable and some of them, I don't like. For example, the main protagonist of the show is Shiroe Emiya. I honestly don't like him because he's a stubborn teenager that makes me want to punch him because of how frustrating he is. Another main character of the show is Rin Toosaka. She is a Magus and a Master of Archer of the 5th Holy Grail War. Now this character doesn't piss me off because she's a smart character and doesn't do things that will annoy the crap out of you. There are also servants in the show. I'm only going to introduce one. Saber is the servant of Shiroe and was King Arthur in the past life. She has an invincible sword which is pretty effective at combat. In Fate/Zero, Saber was one of my favourite characters but in Fate/stay night, she wasn't. She somehow turned into a romantic tool for Shiroe but that's not the only reason why I don't like her in Fate/stay night.
Enjoyment (6/10)
The reason why my Enjoyment rating is not below 5 is because of the story. The score would have been a lot higher but the terrible action scenes, mediocre soundtrack and the lack of funny moments is what prevented my Enjoyment rating to be higher.
Overall (6/10)
Overall, the anime has a decent story but suffers from terrible action scenes and the other negative stuff I mentioned above. You can give this anime a try but if you prefer actions scenes with good soundtrack then this is not a show for you. However, if you don't care about actions scenes or epic soundtracks and want to watch an anime with a decent story and slow story pacing then this is the show for you. Prepare to be confused at the story and expect some plot twists.
Pros:
-Decent story
-Slow-story pacing which means it takes time to explain what's happening
-Good Characters
-Decent Character Development
Cons:
-Mediocre animation
-Mediocre soundtrack
-Terrible action scenes
-Ending is not that great
-Main Protagonist can sometimes piss you off
