It's working-class England, 1960. A Jamaican family moves in next door to the Jewish Wisemans, whose young David (Sam Smith) is a kid so wide-eyed he likes to exclaim ''Wondrous oblivion!'' to self-diagnose his own wide-eyedness. Soon David is learning a lot about cricket and racial tolerance, natch from his good neighbor (Delroy Lindo, who's the best thing here). Wondrous Oblivion goes awry in its sloppy racial drama, and although the cricket-training montages are good, they're still training montages, and this is just that kind of overfamiliar movie.
