Humor:
There...is humor content involved.But in the later part of the plot,the humor content is usually interfered by serious "stuff" the next second which kinda hampers the mood :P

Overall:
This Anime is quite enjoyable to be honest.The combat scenes might be some what short but their well drawn one way or the other. (I always get stuck at writing the Presentation since I written everything else in Story,Sound & Art T_T ) Either way,it's going to be troublesome to follow the entire plot of the series since...well read the Trivia section...

Trivia:
-Fate/Stay Night (Anime) was adapted from the Adult Visual Novel version which is being cut into several phases.The Anime version is a highly compressed version of the visual novel.HOWEVER.

When this show finished releasing on the internet I was seeing buzz that it wasn't up to Type-Moon par. My thought was that was quite possible when it's "par" was Tsukihime. But I must say after finishing Fate/Stay Night I find that it exceeded its predecessor in many areas including the most important thing, enjoyability. The plot was simple yet fun to see unfold. You can easily empathize with many of the characters and seeing their interaction is pure entertainment. Ear and eye candy all around to boot. There really wasn't much more that this show could have done to be any more entertaining than it was. In fact if there isn't more done with this property I will be sorely disappointed. I am even hoping that the game can catch a license, although that seems highly unlikely.

Although they left out some plot points from the game, they did an overall good job of integrating 3 route's storylines into the anime storyline. The way they artistically hinted at Archer's true identity was impressive, they didnt want it to focus on Archer as it wasnt his storyline, but they gave enough hints so that someone could figure it out if they paid attention to the show and thought about it for a while. The storyline flows nicely and concludes with a sastifactory, if very sad ending. One cant help but keep watching to find out about Shirou's progress in the war until its conclusion.

Humour is there, and is very good. Fuji-nee is the clusmy sensei and makes a very good comic relief character, and in the later part of the show Illya has some of her moments.

Because I have never played this game before, so I have no idea what kind of H-game it is. However, according to what I've known, the story line is just a small piece of the real game Fate. Each character's identity was not very clear; therefore it is very simple for game player. Sometime, this game can also be too enigmatic for normal watcher because there were very few details about servant's true identity, how they used to live, and why they became servant, or what happened in the first and second war. In addition, the relationship between Sakura and Rin still remained mysterious even till the end of the anime, Saber's identity was just fragments through her dream and many more.

Though the conclusion of the anime was quite predictable, I did enjoy watching the series. The action was what kept me hooked. Again, being based off a H-game there wasn't really anything too great expected, however for those of you who stopped watching Naruto and/or Bleach due to fillers, you can choose to pick up this series to help cope with the missing action from your viewing library for the time being.

The anime itself was not strictly all action, there were parts of humor, parts that were saddening, and parts where only dialogue was very intruiging. In the end, I'm sure those who start and finish the series will be fairly impressed with the final product. There was always something happening each episode and at the end kept me wanting to watch the next one as soon as I could.

Some characters specialized in niche area of the story.

Fujimura seems to control the slapstick comedy aspect whereas Rin 's role is sacrastic humor department, does liven up the otherwise a dark story. Saber was more like non-chalant humor generator.

The concept is slow build up to an epic ending as the gamestory does showing how Shirou tribulations before he become a true hero in protecting people that he loves. Thus the numerous discussion or talky scenes is essential in creating plot devices to push the story forward.

The anime seems to alternate between discussion phase and brief if spirited action sequence. The anime makers is trying to strike a balance between these to address the complexity of the story.
