Just finished watching Fate /Stay Night a few months ago and it's really quite a nice anime. It's just a pity that the story didn't really developed. It had the potential to be a 50 episode series coz of it's complexity and vast amounts of characters involved. Instead they chose to make it a 24 episode anime and rushed through many of the concepts in the show. Nonetheless, it's still a good anime and i would still recommend it.
Below is an opening video of Fate / Hollow Ataraxia, which is a sequel to Fate / Stay Night. Enjoy.
