Im not that of a crazy anime fan or such, i just like amazing stories. Well, you got one of the finest here.
At first the show starts slow and kind of childish, but as soon the story develops, it transforms into a quite deep and emotional one.The pacing of the story, the way they play with time in both storytelling and the plot itself is just superb.This show got all packed just right: drama, romance, sci-fi, action and comedy. The music is good. The animation is quite nice and i agree that the voice acting is outstanding, specially with the "Mad Scientist", he will become in one of your favorite characters ever, i can tell you, he is incredibly well developed. And for that matter, all the other characters are very well made too, you will feel emotionally connected to them. The premise of the show has some deep philosophical meanings: If time travel would be possible, Could a man escape his fate? What would a man do with almost divine abilities? What does the time really mean? At the end of the show, i was left thinking about the immanence of our existence and many other mindf*cking stuff.
If you want a really, really outstanding show, you don't have to look to another place.
