'Guess Who' signals social progress or cultural decline?

The rest of Guess Who is not nearly so reckless, but its blandness has less to do with caution than with comfort. In its easy, affluent setting, what prejudices remain can be shrugged and laughed off. Guess Who suggests, convincingly enough, that race relations (to use a quaint-sounding term) have gotten a lot better since 1967, which may be one of the reasons this movie is so much worse than its predecessor.
