But no matter what flaws you may have or how much you screw up, at the end of the day your friends will be there for you especially when you're there for your friends.
It doesn't matter who or what you are, you're still going to mess up. Even though Finn is the only human in the show, everyone in the show makes human mistakes. If any lesson can be taken from this show it's that nobody is perfect everyone has their flaws. The characters are messed up in the best way possible. It starts off supposedly trying to teach you something, but instead saysscrew it and veers off into AWESOME. Adventure Time does not teach lessons per se. I saw the pilot a couple years back and finally saw the show and i was blown away.
But nonetheless, this show is the best cartoon I've ever seen. Not adult swim but on during the regular hours.
