But when a movie carries a PG rating, it means Parental Guidance suggested for a reason. I HATE when PG rated movies are G rated with a fart joke. They altered the song "New York, New York" to have "Heck" in it for Madagascar 3... nothing in that movie seemed remotely PG-ish. Wasn't even dark.
Meanwhile, Rango had mild cussing, dark situations, and adult humor. THAT was PG. Remember the TMNT movie from 1990? Raph was constantly dropping the D bomb, not even subtly, and there was a crap load of heavy violence? The 2007 one's violence was toned down, and not a D was uttered, not even once. yet, cussing was all over PG rated Speed Racer.
