My colleague Helen Chernikoff, perhaps sensing my delinquency of late when it comes to “In the Mix,” has written a thoughtful post for “The Yad,” our new staff blog. Helen explores the somewhat outdated intermarriage motif in Judd Apatow’s movies, most notably the currently-in-theaters “Five Year Engagement.” Check out what she has to say — and check out “The Yad” in general, especially on Fridays when yours truly posts. (Today’s post won’t happen ‘til later this afternoon, however.)
