Beware of slight spoilers from here on.
The story is fairly simple: an ordinary high school boy is fighting for his life, those of his friends and eventually for the fate of humanity itself. Personally I think that's where the strong point of the anime lies, the battle about what should happen with humanity in the end. The world is put through 7 days of trials. If humanity survives this, they can request an audience with the "god" of this world and get their wish fulfilled. But with the fate of humanity at stake, which wish is the right one?
Yamato Hotsuin thinks that those with power and talent should rule and doesn't think twice about sacrificing people for the greater goal. The rebel leader believes everyone should be treated equally yet has to admit that Yamato's radical actions work. During the battles and life threatening situation our main character has to find the answer to the question "how should humanity advance after this?"
Now I won't say the anime is a very deep psychological one, it doesn't seem to want to be one, but if you think about it, the story itself is rather interesting. Sure, the rushed pace and the "obvious" choices the main character makes aren't ground breaking but honestly; they're very human-like. The main character is a normal high school boy whom suddenly, without him wanting to, has to decide the fate of humanity itself. He isn't like Lelouch or Light, he isn't driven by some ultimate goal nor has he ever wished for things to turn out like this. He's simply a gifted with power and bound by "Noblesse Oblige". And that's what makes him, if you ask me, so likeable. He's a normal high school boy whom simply doesn't want the people around him to get hurt.
Art: I don't know anything about "fluid" animation or high quality movements but my personal opinion is that everything is fine. Sure, there are shows with better and smoother animation, yet there are ones with worse ones. I like the character designs a lot and the colors they used for the anime.
Sound: The background music is well done and fits the atmosphere of the anime. I especially like the ending, for some reason it seems to really fit the overall feeling of the anime.
Overall Enjoyment: As I said earlier, the story isn't very complicated yet if you're willing to think about it yourself, it's actually rather deep, I personally liked that a lot. The characters are fine, not everyone gets a chance to develop through the anime as much as I wanted to yet they're all likeable enough. There is enough action and even though it's a bit rushed; it's honestly a fine anime that doesn't deserve the bashing it gets.
The best point of the anime is, I guess, the fact that the main character seems to be so very human-like. He isn't able to turn a blind eye on someone suffering right before his eyes and his way of thinking might be "simplistic" yet it's also so very, very human-like. Just think about it, if you yourself would be in his position, would you honestly be able to do things differently? I bet most people wouldn't. He's not flashy and isn't overly optimistic, he just tries to do whatever he can to change the fate of his friends. And honestly, how can you dislike him for that?
