I finished Lesbian Space Princess. It was quite unfunny and none of the characters were particularly likeable for me. Granted, I am not the target audience, but even if I was I struggle to think it would be anything above mediocre. I can see why people are hating on it.
Disliking Mushoku Tensei because you find Rudeus distasteful is perfectly valid, but this performative nonsense, casting aspersions on an author because immoral actions don't necessarily line up with negative consequences in a narrative is insane anti-art garbage
