[Up in Seth's Room presents a] cliché situation, with some goopy descriptions of sexual bliss and what might well be seen as a ludicrous solution in these days when technical virginity has pretty much lost its cachet. But one can imagine other girls becoming involved in Finn's lonely battles (defying her parents, disagreeing with Vida, resisting Seth). And the fact that different readers can come out of this taking different sides—Finn's, Seth's, even the parents'—attests to Mazer's skill in giving the single-issue story some human contours.
