If this movie seems sometimes lost in too many story threads, it's because it wants to say something about both the ethics of journalism and the pros and cons of attending health clubs as a way of living. And if it seems at times vapid, empty and without substance, that's probably because it reflects the vapidity, emptiness and lack of substance of our pop culture. It's similar, in some ways, to films like "Cocktail" or "Dirty Dancing", but it's better than them, because it takes some distance from its subject. And, thanks perhaps to the continuous change of locales, or the star presence of Travolta, or the beat of the soundtrack, or the scantily clad Laraine Newman, it is an effortlessly watchable (if predictable) movie.
