As a kid-free adult, I would love that! Sometimes it's hard to tell whether a movie is worth spending a couple of hours on without seeing a few reviews or comments.

But the internet being what it is and all, I'm imagining the inappropriate things people might try to sneak into the comments in the family section, or even people trying to use the comments as an avenue to connect with minors. Streaming services would suddenly have to develop a means to screen and police the content of the new content section, while keeping service cost increases as low as possible.
