Dumb, entertaining show This show is the first anime I can call a guilty pleasure. As many may know at this point, this show looks gorgeous, the action scenes specially are breath-taking and the overall animation is top notch, the concept is... interesting, I guess. And, the most important thing about it (for me at least) is that it's entertaining as f*ck.
And it's not an small thing, there's a lot of "bad" with this series, like the rules of the "game" that can be bend by... anyone basically. Or the bland, stereotyped, absolutely imbecile characters that conform the protagonist and the main characters (Masters, mainly), and the-sometimes-predictable-plot of the overarching story. But the animation, action and charisma from a couple of Servants make the show somewhat worth it.
Is not great, at all. But the way it is able to make itself watchable by having a great look, OK music and a few really interesting characters is an achievement by itself. I can recommend it, just have fun.
