When it was first announced that David Fincher, best known for such meditations on violence as Seven and Fight Club, had taken up directorial reins on a film about the founding of Facebook, it’s fair to say that some film fans found themselves confused. Why had Fincher attached himself to such a potential snoozefest? Well, now we have the answer. With a story driven by sharp dialogue and an unrelenting pace, The Social Network is anything but boring. A beautifully acted character study, it asks real questions about the nature of business, friendship and loyalty – and we don’t just mean online.
