Nora Ephron adapts her best-selling novel (a transparent dramatization of her failed marriage to reporter Carl Bernstein) to the big screen, but in the process falls into the same trap that snares too many filmed versions of popular fiction. In a nutshell, the movie is all dialogue and precious little depth, presenting a bare bones account of marital love and infidelity that skims lightly over the salient points of the relationship without ever scratching any dramatic surface. A large part of its appeal (if not its only attraction) lies in watching the not inconsiderable combined talents of Meryl Streep and Jack Nicholson, but the popularity of the two stars only undermines their ability (with a script this thin, at any rate) to effectively ply their trade. Viewers will see the actors, not the character each is supposedly portraying, and if proof were needed try to recall in detail afterward anything about their respective roles.
