As a kid Power Rangers were off limits. I can't tell you how many times I got caught watching it. I know my mom was not allowed to watch The Flintstones or the Jetsons because of how they talked, lied, etc... Disney movies were always OK, which surprises me now considering how much magic is in them.
In my house growing up TV was never an issue. I remember my parents allowing us to watch R rated movies. The issue in my house was always music. Talk about double standards! We could watch R rated movies but some of the most harmless songs we couldn't listen to. Even the radio was 99% of the time off limits at night!
