Natalie Portman and Ashton Kutcher in No Strings AttachedNO STRINGS ATTACHED

Against all expectations, at least my expectations, director Ivan Reitman's No Strings Attached is a perfectly enjoyable piece of midwinter fluff, engaging and breezy and of no consequence whatsoever. Yet I'll admit to being somewhat shocked when, two days after seeing it, I replayed the notes I quietly recorded during my screening, and discovered that I didn't whisper even one criticism or complaint in the whole of its 105 minutes, which is a claim I can't even make about The Social Network.

Then again, the movie is a formulaic romantic comedy starring Ashton Kutcher, so I suppose the complaints do take care of themselves.

Anne Hathaway and Jake Gyllenhaal in Love & Other DrugsLOVE & OTHER DRUGS

In my 2009 review of the director's turgid World War II drama Defiance, I opened by asking, "Am I the only person who wishes that Edward Zwick would go back to making sharp, bitchy comedies like his 1986 Rob Lowe-Demi Moore romance About Last Night ... ?" Well, less than two years later, Zwick has returned to those romantic-comedy roots with Love & Other Drugs. Because, apparently, I needed another reminder to be careful what I wish for.
