Anvilicious: "An American in Palomar" concerns a U.S. photographer who visits the village intending to produce an exploitative book of photos showing how supposedly downtrodden and abject the residents are. The story spells out his intent, and his failure to understand Palomar's culture on its own terms, with third-person narrative captions emphasizing how arrogant he is. In the end, having slept with the naive Tonantzin while allowing her to assume he can give her a break in Hollywood, and having thoroughly annoyed the savvier villagers, he is beaten up on the way out of town, experiencing a moral epiphany as he blacks out. Gilbert himself later admitted this wasn't one of his subtler efforts.
Bizarro Episode: "Birdland", the Palomar story published under Fantagraphics' Eros imprint, is a bizarre pornographic story involving alien abductions, hypnotism, and the Orgone theory. While Fritzi and Petra play important roles in it, its connections to the rest of the series are virtually non-existent, and it's never been mentioned since.
Values Dissonance: The series' casual approach to nudity extends to child characters as well as adults. This has occasionally resulted in the books being challenged in libraries in more conservative parts of the United States on the grounds of being "child pornography".
The "Locas" stories contain examples of:
Growing the Beard: Many critics pinpoint "Vida Loca: The Death of Speedy Ortiz" as the arc in which Jaime's narrative and characterization skills first reach maturity, following his shift from SF action-adventure tales to realistic depictions of Mexican-American urban life.
Jerkass Woobie: Vivian "Frogmouth" Solis is loud, obnoxious, sharp-tongued, quick-tempered, and moody, and has a knack for getting herself in trouble by hanging with morally questionable individuals. Despite this, she shows moments of genuine vulnerability which endear her to Ray and Maggie even as she often frustrates and angers them.
