It's not just you, Anon.
I'll always remember it as a personification of Adventure Time's raw, untapped potential: Kindred spirits, just being themselves and doing what they love, without any rules or social limitations enjoying life and living it to its fullest. No stops.
In an age where everyone is so obsessed with with image and public morality it's easy to forget it's not only about what something is but what you do with it. AT lost that magic a long time ago.
