@DEVILinIRON: It's one of the cartoon shows that I felt was better before it got too lore-focused. Kind of a problem with a lot of recent cartoons actually. Everything doesn't have to be super-deep lore dump shows. Jake the Dog & Finn the Human were an odd due, but kept the show entertaining. Also, the final season was rush out the door and it became lackluster.
I think it also needs to be mentioning that it was probably the most historically important show of the 2010’s. It revived cartoons for that era that got CN back on track, popularized minimalist design again, and started the “lore dump” cartoon.
I actually own the entire series on Blu-ray. Just started buying the first couple of seasons for the sake of it and ended up going for a complete collection. I'm definitely curious about it. May not be up my alley completely but from the handful of episodes I have seen, it's not too bad.
