Rick and Morty
I can imagine some of you have already seen/heard of this show but seriously, This is the best show I've seen a very long time. Extremely funny and creative - I mean it's so frigging OUT THERE with it's ideas. The characters designs especially. It's also so well animated and very quotable. Pretty much every episode has a line which gets you.
It actually gives me a huge Futurama vibe which is just the best. I guess it's because there both sci-fis. But both of those shows I find.
E: OH! One of the most interesting things about the show is how they use infinite timelines/universes a lot. Really gets you thinking y'know.
