A whole slew of beautiful and sexually vulnerable women are trying to break into the TV news business, and there are just as many men trying to break into them!

Is anime seen as childish in Japan?

That prejudice will never die, in any country.
But I have not heard/read/come across anyone berating an adult anime watcher or cartoon reader in… years.
I guess that’s something.
With this much quality disparity between live action and anime, I guess you will just sound old fashioned with that prejudice.
