The Rise Of The Kid Flick?

That's Steven Zeitchik's view:

Families are the ones going to the movies these days. Perhaps the only ones.

That's not just a summer phenomenon. Almost every big hit among the 2010 releases has been a movie whose primary, if not overwhelming, audience is children 12 and under -- "How to Train Your Dragon," "Shrek Forever After," "Alice in Wonderland." Ditto for the year's biggest sleeper, "Diary of a Wimpy Kid." In fact, there isn't a single big-studio movie aimed at children that failed, save perhaps for "Marmaduke" (and some would argue that wasn't a movie).

The Atlantic's James Parker recently reviewed "Diary Of A Wimpy Kid."
