I’ve really been enjoying Adventure Time lately, so I’m glad to hear this! I don’t know why I didn’t watch it when it originally aired but I’ve been missing out; I’ll be checking this show out once I finish up for sure.
Oh man you are in for a ride! Like the other person said, the first couple seasons are kinda cute random fun so they can set up the world and introduce all the characters. They slowly start building up into a crazy mind bending storyline around season 3 but more so around season 6 and it’s sooo good!
