Content Ratings

I don't understand the ESRB ratings movies get nowdays. I've seen 'slime' contribute to an R rating. I don't understand it. Am I the only one not repulsed by slime? Don't people routinely get slimed on Nickelodeon? Should that be rated R?

Now I see 'quirky situations' contributing to the PG rating on Willie Wonka. What gives?

The one that really makes me wonder if Hollywood is not making fun of the whole rating system is when I see 'thematic elements' as contributing to a rating. What is a movie, if it is nothing more than a whole series of thematic elements?

If I ever see 'colored light and sound' as criteria for a rating, I'll know that they are making fun of the system. Till then, I'll just suspect that they are.
