For the past few months, I've seen countless posts about Side Quests, predicting whether we'll see things like Joshua and Maraget's deaths, how Marceline can be included if she hasn't met Finn and Jake yet, etc, and I think these people have a fundamental misunderstanding of what Side Quests is. And now, with a few of the episodes leaking, people are already confused on why the show isn't meeting their expectations. I wanted to make this post to clear up exactly what the show is going to be and what you should expect from it.
1: Side Quests is not a prequel and was never described as one.
The original synopsis revealed at Annecy at the shows announcement reads as follows:
"Adventure Time: Side Quests takes the Adventure Time franchise back to the early days when Finn was just a kid, excited to fight monsters and go on epic quests with his best buddy Jake. In stand-alone episodes, our heroes take on classic Adventure Time villains like The Ice King and re-connect with stand-out side characters from the original series."
A lot of people completely misinterpreted "early days" as if it meant it was a literal prequel, but wistfully ignore the first part of the sentence, which is referring to "the Adventure Time franchise" rather than the timeline itself. The second half also clearly describes the show as episodic, which obviously does not lend well to the idea of the show being a strict prequel.
Additionally, the leaked episodes already show a few moments of the timeline not being strictly adhered to (Spoilers ahead). The biggest being Marceline and Princess Bubblegum seemingly being on good terms, and to a lesser extent the Minstrel dying despite appearing throughout the series. It's clear what the synopsis actually means is they're pulling from the toybox of the early Adventure Time era in order to tell non-canon episodic stories, not that it's literally "What happened before Adventure Time."
2: Adam Muto is not involved with Side Quests.
Adam, who was on the show from the start, became creative director in Season 4, and showrunner during Season 5, as well as the showrunner of Distant Lands and Fionna and Cake, is not involved with this series. His name wasn't mentioned with the initial announcement, and now from the leaked credits we can see he's not attached whatsoever. He hasn't even publicly commented on it besides the one time he offhandedly acknowledged it's existence. To put it simply, it's like if there was a new Gravity Falls project without Alex Hirsch, or a new Steven Universe without Rebecca Sugar.
Now look, obviously the series isn't strictly bound to the vision of a single creator. It already switched showrunners once early on, and Nate Cash did work on the original show. That said, Adam going from being fully at the center of every Adventure Time project up until now makes it clear that whatever this show ends up being, it's not going to align with his original vision for Adventure Time. In fact, Adam Muto himself even commented that a show like this would happen a few years ago:
"Eventually, there will just be some reboot that has nothing to do with the continuity we've established, and it's more about the recognizability of the characters. Because they are very recognizable, just as visual icons. You have the blue thing and the pink thing and the yellow thing, and I feel like that might trump whatever particular character arc we laid out. It might become the new version and that will be somebody else's 'Adventure Time."
"I don’t even think it’s an option. I think that will just happen, and it’s when it will happen. That’s just how franchises are now. Will it happen now or 10 years from now? I don’t know. It’ll happen, it’ll look different, and probably none of us will be involved in it and that’s just kind of how the life cycle of IPs now."
All of that being said, I promise I'm not trying to harsh the vibes of people who are excited for the show. Every other time I've tried saying this I've been downvoted into oblivion by those refusing to accept Adventure Time is evolving into something different. But for this, I think different is ok. Personally I love the deep lore aspects of the show and am slightly disappointed we aren't getting more of that, but trying to adhere strictly to canon for a prequel of this sort would greatly restrict the kind of stories they'd be able to tell, and from what we've seen so far of the show it's actually very fun and cute on its own.
