>>93174796AT, and specifically fin reminds me of my former self, always happy optimistic, everything exists in some shade of rainbow, everyone has good intentions and does who don't are only misunderstood people.
As the series moves forward all these kind of ideas slowly die in small plot elements, from a small random quirky animal being animated towards its dead to a fun charismatic character devolving into a more obscure shade of its former self.
I went through a lot of shit in late 2015, and adventure time was one of the only few things that kept me up float on that time, rewatching the episodes only revive those same emotions, those bittersweet emotions, the sweet feeling of being able to grow up without stopping looking backwards to the former naive self.
I dunno if the staff of AT made it this way or it was just some random miracle, but this piece of animated media has itched in the deepest corners of my soul in a way I had never imagined was possible.
