I honestly think it’s just a good reason to always qualify your preferences. There are dozens of anime for which, if the conversation turned to that anime specifically, or even a major theme, I’d happily talk about it. But most of it really is complete trash. Honestly you can say that about most media which isn’t “Christopher Nolan films.”
Also, that’s not to say complete trash can’t be entertaining or have some marginal value. But anime does have a serious problem with sexualizing children, and that definitely keeps it at arms length for me as a general topic.
SAO is the worst fucking offender. The first half of the first season is top tier, but then the fairy shit is almost unwatchable. And then they keep going back to the awful fucking fairy world in every sequel. It almost felt like it was done out of spite.
