A man attempts to grab a woman's butt, and there are two closeups of her butt in very tight leather.

A woman and alien fight, and they grind against each other unintentionally.

No sex or nudity of any kind, but an alien does attempt to rape a woman with no avail.

Some strong, gory moments here and there such as a character getting ripped in half, a decapitation (LOTS of blood), humans and aliens alike being dismembered, and ninja fights (violent, but not very bloody).

Very mild language at first, but in one scene the f-word, including motherf***er", is used dozens and dozens of times in just a little over a minute. "Pussy" is also used in a sexual context.

Nothing.

The movie isn't very scary or intense (it's all very over-the-top and tongue-in-cheek), but some of the gorier or grosser moments may be a little much for certain viewers.
