Sorry I didn't respond earlier. Kept meaning to dig out my copy.
First of all, you should know it isn't a very good movie, very average TV-movie-quality, at best. The rating is for maybe eight or nine uses of "fu*k", a couple "sh!ts", and in the introduction to the Meg Ryan character she is in bed, naked, and when she rises you can barely make out her left breast from behind and the side. Scandalous. There is a bit of blood for a gunshot wound in the overwrought finale, and that's it. I'd consider it a very soft R, though I don't have any idea how sensitive you are about such things. I'd wager any two episodes of
"Law & Order: Special Victims Unit" are exponentially more disturbing than everything in
Promised Land.
And don't get the wrong idea from the publicity photo above: that has nothing to do with the tone of
Promised Land. Gedrick and Pollan are really the main characters, and Ryan plays a tattooed drifter with psychotic tendencies and, for her first sections of the movie, pink hair. It's a zillion miles form a Romantic Comedy and a pretty lame entry in the coming-of-age smalltown drama category.
Mostly I'd just dissuade you from watching the flick because it is so utterly pedestrian and forgettable. For example, Sean Penn's
The Indian Runner (1991) has similar themes and is
so much more interesting and compelling. Or an earlier movie Penn starred in,
Racing with the Moon (1984), which is a '40 period piece but again similar themes much better examined.
But, to each their own.
