Where are the parent review sites?

If someone knows of a website where I can find out what movies and video games are appropriate for kids please let me know. Yes, I've seen the Movie Mom and it's not what I'm looking for. What I want is a site that lists what I will see in a movie. Does Joker call Batman's girlfriend a b***h? Or maybe the actor in a PG movie has a partially nude sex scene. Yes, I know IMDB gives me some of this stuff, but it doesn't go far enough.

And what about video games. If something is T for teen occasionally its just for blood and sometimes its for language or sexually suggestive material. And yes it does say it but the degrees vary in my opinion. I'd like someone to say: "the skateboarder will fall on his head and blood comes out, but you can turn that feature off so it makes the game less violent." Or something like this: "the guy runs around with a chainsaw and chops off zombie heads."

It's a niche that is wide open--who is going to fill it?
