PG-13 movies you wouldn't show to kids/R-rated movies you would?
What are some instances of you disagreeing with the MPAA, when there's either a PG-13 (or lower) film that exists that you wouldn't comfortable showing to kids, or when there's an R-rated film that would? Here's mine.
PG-13:
Casino Royale
The Social Network
Daredevil
Juno
Easy A
R:
Face/Off
The Matrix
Panic Room
The Happening
Kung Fu Hustle
What's yours? I'm especially curious for those either are parents or are planning to become parents soon (I'm neither, FYI).
