The Legend of Vox Machina
I discovered it by chance, never heard of it before, but damn I want more !! (And luckily seems like more will come !!)
It's a Fantasy cartoon based on Dungeon&Dragons, like many others lately, but for now it is the best I ever seen !!
The language is modern, and the jokes are not for kids, but even if I wasn't aware about the "making of", I knew there was something different from the other cartoons while watching it... reminded to me the same kind of stupid things that happens during a real D&D session with friends...
And it is indeed the result of real play sessions between professional dubbers, that started just as a podcast, and then became a cartoon.
I liked everything of it, the drawing style, the animation, the music, the story, and damn, I don't know how many times I was like "that's a classic, I already know how it en... WTF !! O_O", or started laughing by myself.
It contains also things that normally I really hate, some little "musical" and songs (them could ruin an entire movie if present, example: The Hobbit), but I found them "acceptable" in the way them are presented here.
