For those of us who are not predisposed to spend hours of our time spying on birds in a forest, birding aficionados can seem like an awfully strange lot. That’s not to suggest that their hobby isn’t understandable. After all, the satisfaction in finding a rare bird seems similar to the sense of accomplishment one feels upon finishing a difficult puzzle, or upon finally locating Waldo. Still, anyone who’s ever accompanied a birder on his mission knows that once the object of prey is spotted there will be a long, frenzied staring and photographic session, with any slight movement met with enthusiastic “oohs” and “aahs.” If you’re not of the niche birder community, this is an insufferable experience. So it’s hard to fathom why director David Frankel and screenwriter Howard Franklin imagined anyone would be especially entertained by a movie about it.
