A parent's guide to Deadpool (in an admittedly conservative community):
Not only does Deadpool like to destroy his enemies, but he likes to do it on screen. There is plenty of blood, gore and violence to really go around...
The language is harsh and constant throughout the movie...
The film includes full-frontal male and female nudity, a constant barrage of raunchy sex-related jokes and an extended sex scene that lasts several minutes and contains a few things I'm not totally comfortable mentioning here.
