This Shortcut displays Common Sense Media ratings.

Common Sense Media reviews appropriateness of media for kids. This CommonSense shortcut displays age rating, the parents and kids say age ratings, the individual content ratings, and an excerpt from the "What Parents Need to Know" section.

It takes dictated input and a text dialog for comfirmation. If no result is found, a notification will say so. Otherwise, the info is given in a dialog, with an option to open the page in Safari.

You can duplicate this shortcut and make it for TV rather than movies (the default) by changing a value in the import questions / customize this shortcut section.

Here's a screenshot of Common Sense.
