Or the people who say that are obsessed with subtlety and want everything to conform to the Western standards for art due to cultural hegemony brainworms? Sometimes I feel very guilty for engaging with this sort of media instead of something more "serious"
anime has plenty of incredibly subtly told stories. watch utena, which is a great mix of subtle and blatant with massive amounts of space for interpretation
and being unsubtle isn't bad either, sometimes it's good to watch something that has the character openly discussing the themes, like ghost in the shell or the climax of every gundam
