Here is something to read. I was contemplating the same thing the other day.
If you are too lazy to click the link, it is about movie ratings, specifically The Dark Knight movie, in comparison to video games like Condemned.
Although I loved The Dark Knight, I was really disappointed to see them advertising it children via toys and what not. Mostly because this isn't your typical Batman. This isn't the same crappy Batman they see on their Saturday mornings with the Rastafarian Joker. This is a darker, harsher, more serious Gotham and Batman than what we got to see when we were growing up.
Times change I suppose.
