To me that's like saying everyone has to kid-proof their home just in case some parent decides to break in a person's house and abandon their child there.
I don't think everything has to be for kids or kid safe. It's up to the parents to investigate what their children are exposed to.
Agreed. That's why the movie is rated R and all the previews have been of him drinking, doing pot, sitting around with hookers, lusting after women, and basically doing very un-kid friendly things. If, after that, anyone wants to take their 2 year old to see it, they're the dumbest and laziest parents in the world. As much as the story seems like out of a 1980's kids movie (the satire Seth was going for), it isn't for kids. Though I will say the previews hide the fact that there is a reasonable amount of sweetness in there.
I openly despise the thought that animation is a kids only medium. It never really was. I don't think any kid of any age from any era would have had much enjoyment in Betty Boop cartoons... and the Tex Avery Big Bad Wolf and Red Hot Riding Hood cartoons were made specifically as entertainment for WW II soldiers before being shoved into Kid friendly TV compilations. I think that's the problem right there... the advent of TV solidified the fate of cartoons being for kids at some point. Definitely not the Flintstones, though.
Sure, there are a LOT of poorly made, slap dash, shock humor crap that follows in South park, Family Guy, and Adult Swim's footsteps (remember Striperella? Other than being a titanic failure?)... but I'm not going to deny the actual good stuff for not being appropriate for all ages.
Heck, even in the all ages stuff, there's a crapload of adult innuendo that rarely gets picked up by the censors. Only times they really hit are Rocko episodes (Rocko working at a Phone Sex line and grabbing the wrong kind of berries) and that Cow and Chicken that was just written to make fun of lesbians (which is a HILARIOUS episode).
