More giggling goes on here than anyone over the age of 12 – or male – should have to endure. Otherwise, this movie debut of Britney Spears should please her two main audiences: young teen girls and the creepy men who ogle them. As a standard road-trip flick, Crossroads is predictably, harmlessly insipid, but worse is the moral instruction the movie tries to offer. There are warnings here about everything from drinking to pre-marital sex, even as Britney indulges in both. The result is the sort of mind-boggling clash of messages that defined Spears’ career.
