On the surface, the movie seems to celebrate iffy behavior. But at the same time, several human heroes do learn empathy and tolerance toward the alien visitor. Ultimately, this is one of those stories in which a laid-back character attempts to loosen up an uptight, repressed character (or, in this case, two uptight repressed characters).
Positive Role Models & Representations
Fantasy violence includes some comic fighting (including a bar fight) and some shooting, with gunshot wounds. There are also some threatening characters, an image of the alien eating a bird, and the suggestion of a hurt dog.
A nearly constant stream of sexual innuendo, mostly for humorous effect. At a comic convention, the main characters check out several sexy "Princess Leias" (in costume). A drawing of an alien girl with three breasts is referenced several times. A shot of the alien's naked buttocks.
Near-constant use of "f--k" and "s--t," plus "p---y," "c--k," "c--ksucker," "ass," "son of a bitch," "hell," "t-ts," "pee," "Jesus Christ" (as an exclamation), "butt," "d--k," "prick," "damn," "crap," "goddamn," and an image of a raised middle finger.
A mention of Reese's Pieces in reference to E.T. Since the movie begins at a comic book convention, there's also a stream of various references to comic books and other sci-fi stuff.
Ease of Play
The alien smokes both cigarettes and pot; he shares his pot with one character, but it proves too strong, and she passes out. The main characters also drink beer and get drunk.
