A lot of gore, violence and language for a PG13 kids movie

I watched this and at times i did not know what ages it was meant to be aimed at! I thought it was meant to be like Goonies, a kid's family film, but its not, in fact this movie is sometimes R rated!

First of all we have language, a kid calls Horace "faggggot" and "whore-ass" a few times and later Horace says "tits!",, Dracula calling a 4 year old girl a "bitch" , not suitable for kids.

Then we have blood, vampire brides are eating bloody raw animals, the GillMan gets shot with a shotgun and you see red blood, The Wolf Man explodes and you see his limbs, head, arms etc with blood everywhere.

Kids are strangled, some high-school girls are kidnapped by Dracula, locked in a closet and then turned into his vampire brides, and then later shot/staked killed...! Poor girls!

And Rudey is a pre-teen smoker!

It's quite extreme for children, while at the same time has a comedy/family fun value to it (for example when the kids play with Frankenstein, it's a fun light hearted montage).

I guess times have changed and you can't show things like this in a PG13 movie anymore. It's a very cool PG13 movie, i am just wondering whether it was supposed to be aimed at children or young adults?
