Easily one of my favourite animated shows of 2023, Carol and The End of the World is a very pensive and surprisingly mature show compared to the usual adult comedy cartoon schlock.
If you are looking for the next Family Guy, or Big Mouth, best let this show be and go check out other things because this show isn't got you, but if you are looking for a relaxed and pleasantly animated experience with a dash of humour and a lot of heart, this is the show.
Not every episode is perfect, and it does occasionally dive a little deeper into cringe comedy territory than I would usually recommend, but the show is at it's best when it lets the characters simply interact with each other in emotional and genuine ways--sometimes with complete sincerity and sometimes with a bit of comedy.
The show also looks very nice. It manages to take the usual adult animated comedy style and inject it with a whole lot of visual flair through unique character design, impeccable colour/lighting, and some beautiful animation.
Overall, it's a moody, pensive viewing experience that experiments a lot with the the structure of storytelling and uses the animated medium to it's advantage. It won't be for everyone, and it makes no attempt to appeal to a general audience, but unlike so many adult animated comedies that are driven by derision and hate, this one is driven by love and compassion. And in the face of a world ending apocalypse, that's what is truly important.
