An intelligent movie, indubitably.
Though I would debate the pronunciation of a few of the names, it's clear you're done at least a little research on the history of philosophy. What surprised me was how you could convey it so it would not bore simple ears, and yet still question the well learned.
The credits provided much needed comic relief after being slammed with information for ten solid minutes. I've thought about all of these things myself, and many others since I read the book "Sophie's World" by Joseinn Gardner (spelling of the authoress may be a bit off). I highly recommend it to an intelligent mind like yourself, and any other that may be out there.
To resume commenting on the movie, I felt that the character design and graphics were both unique and adorabe. I think the movie needs a pause button, just to take a break and to either ponder or otherwise. Also, while I appreciate the lip sync and varying expressions of the protagonist, our beloved Da Dinictus, I think it's a reasonable assumption for people to be more concerned with reading the subtitles than interpretting his facial quirks.
Finally, moving on to challenging the ideas presented in the movie itself, I can't say there's a great deal to challenge at all. There were more questions than statements, but I do debate one point you brought up. If everything is predestined, if we have no choice in what we do because someone or something already planned out our lives, there is still meaning. Because we do not know our destinies, what's going to happen next, we have the ability to make choices that will, theoretically, ultimately lead us to fulfil our fate. Choice is an illusion, but because we can't prove that, we're happy believing we have some control of our own lives.
Personally I'm not for existentialism. I had to look into it for a high school project last year, and when I had finally sorted out my thoughts after days on end, I realised I was sick of the notion. You're right though. Without hope, there is no will. Without hope, there is no chance. Without hope, there is no ability, nor reason, nor anything. Hope is a truly wonderful thing. Something to be cherished and nurtured, and something that will refresh us in return. It can be found in each of us, and can bring light to the darkest of places.
"It bends, it twists, it sometimes hide, but rarely does it break. It sustains us when nothing else can."
(those two quotes came from my present wallpaper- it'sj ust a daily reminder that no situation is ever hopeless until one gives up hope).
Anyway, I've given my little dip in philosophy. I hope I've provided some insight with my incessant ramblings. I still have one question, more puzzling, a larger conundrum than I have ever encountered, greater than all aforementioned questions in the film put together;
