I elsewhere made some comments about it being strange that PD is rated M when, even if it is violent, the violence is rather goofy. One thing I forgot to mention in regard to that is the intro cinema to the last Area 51 stage. You break into a lab where area 51 scientists are about to perform an autopsy on a (living) alien. When you save the alien, the scientists try to stop you by releasing poisionous gas. At first I thought this was something unintentionally stupid, but no: It's actually supposed to be funny, I think. The gas eventually kills the scientists right after they realize what they did might not have been a good idea, and Joanna calls them idiots.
