Excerpt: I find it somewhat ironic that the title of this movie is “How Do You Know” when I would have liked to have known how utterly bad this was before I invested two hours of my time in it. Please pardon the run-on sentence. Now before I continue with my tirade, let’s examine some of the facts, shall we? On paper, the movie looks good. James L.
Conclusion: James L. Brooks has directed some funny, appealing, emotional, and perceptive films, but sadly, the anemic 'How Do You Know' isn't one of them. This rambling, passionless romantic comedy is only mildly amusing and intermittently warm, and though the talented cast tries its best, the actors fail to infuse the movie with the energy and chemistry it craves. Even good video and audio and a slew of supplements can't heighten my enthusiasm for this lackluster misfire.
