Outlaw Star. Do I have to spoon-feed to you?!?
Okay, beside the obvious correct answer, there have been quite a few series I've really liked over the years. Currently I'm on the Psycho-Pass craze; I'm almost finished with season 1 and I really like the parallels between it and Minority Report and the whole motif of "Don't even think about it; if you do, you're guilty.". Visually, I haven't been so entranced by the video quality of an anime since Ghost in the Shell, and while there are some stereotypical pitfalls with some of the personalities of the characters, almost every one of them is likable. All in all, it's a good show that has put me back in touch with modern anime.
A boy has the right to dream. There are endless possibilities stretched out before him. What awaits him down the path he will then have to choose; the boy doesn't always know. At some point the boy then becomes an adult, and learns what he was able to become. Joy and sadness will forever accompany this. He is confronted with a choice; when this happens, does he bid his past farewell in his heart? Once a boy becomes an adult, he can no longer go back to being a boy; the boy is now a man. Only one thing can be said: "A boy has the right to dream.". For those endless possibilities are stretched out before him.
We must remember...all men were once boys.
