2008 movies inappropriate for kids?

Hi I know this might be a kinda weird but I just noticed it. I have noticed that recently I've seen a couple of movies in 2008, for example Young People ****. Harold and Kumar Escape from Guantanamo bay, the bank job, zohan, 300, etc. have started showing kinda . Is it just me that I noticed they have shown and even a in Harold and Kumar. According to me its wrong, I mean parents take their kids to movies and they are being exposed to at a very young age. I just wanna know did anyone else noticed this or its just me. tell me what u think....
