you absolute fool the stakes of fionna's story are not 'she can't afford to keep her friend's shop open oh no' it's 'fionna struggling to save the shop is a big catalyst to her crippling self worth issues and unresolved trauma' and that is even enough with the ooo storyline imo. high stakes do not always have to be some big drastic life-or-death plot. sometimes high stakes in a story can be more deeply personal to the character and it doesn't devalue that storyline, even in comparison to another where a character is dying.
in fact, the storylines serve as a perfect parallel to one another. in fionna's world, she is pushing herself to the edge to try and help everyone she loves, because she feels like she owes it to them due to how much of her life she's spend not trying hard enough (in her eyes), and thinks that they will leave her if she keeps failing. in ooo, all of finn's friends are doing everything they can to help him because they feel they owe it to him for the fact that he's spent his entire life helping them (as well as just being loved by them, in the case of the main crew, but my point stand more for all the other citizens). and really, how exactly do you expect the stakes of fionna's story to be similar to finn's? the whole point is that hers is a mundane world, and the problems faced there will be more mundane. that doesn't mean they aren't still high stakes.
idk man if you can't see how a character having to deal with the fact that she feels like everyone she loves would be better off without her because she's 30 years old but still has little agency or control over her life and feels that she is actively hurting everyone she loves, while also grappling with the harm she did cause in season one, maybe you need to stick to cartoons for little kids instead of one aimed at adults.
also, the stakes of the ooo storyline honestly do lose a little of their height when like. we already know finn isn't going to die. yes, they're trying to trick us a little with having him get quickly aged up, but there are a lot of other parts in together again that don't match up with the timeline of &c season 2.
also also why does this guy just keep having the worst takes on this show. what is his problem.
