Why do PG?

We have decided to do a PG as we thought there is more ideas and themes we can follow and less restrictions. This will make it easier for us to come up with an interesting storyline and we are more likely to know what the target audience prefer as we are closer to that age group. We decided not to do a U rated film as it would limit lots of our ideas and we would have to be very careful not to push the boundaries of a PG.
