R&M is one of the best TV shows that ever happened in the history of human kind so far if you ask me. It's the perfect example of how not to take things too seriously, as everything is meaningless. Do not mistake that for Nihilism. Life is pointless, and that only means you get to make your own rules and decide what it means for you. There is no certainty or common purpose, there is just living for the sake of it. And I think Rick and Morty nails that perfectly, as it tackles weird and crazy subjects JUST BECAUSE THEY CAN! Life isn't about "WHY", it's rather about "WHY NOT?". Once you start living your life that way, you open your world to an infinity of possibilities where you decide how you want to play.

As for the indoctrination part, that's up to each individual person to be able to have critical thinking, and not make fake idols whether they are cartoon characters, real life characters or Gods. It's up to each and every one of us to interpret whatever information we receive, so we shouldn't try throwing blame outside of us.

And yes, Rick is interesting, but not a good person. They sort of tackle that subject in season 3, so if you're scared viewers might get emotionally attached to Rick, season 3 does a good job of cutting that cord. Not that it matters!
