The MPAA needs to retire the G rating.
I mean, is there ANYTHING - one thing - about this trailer below that suggests that the PG rating is informing parents of anything? "Scary Images and Mild Peril"? Might as well tell parents "This has a story - BEWARE!!!! BE-WAAAARE!" because it makes the same amount of sense. Is there one parent - just ONE parent - out there that sees the PG rating on this trailer and thinks "No way - I will NOT bring my 3-year-old kid to see such scary images and mild peril no matter how much they want to see this!"
The arbitrary nature of rating a film G or PG is completely absurd at this point. If nothing is actually G, then PG for all intents and purposes IS the G rating, and having both is beyond pointless.
Just retire the G rating MPAA and demand all films have some text to warn of something like "mild peril", because you've basically done that informally anyway.
