Annie Hall
Twenty-five years it took for me to get around to watching that flick; there should be a law against such negligence. This is the definitive relationship flick. A film, and this has been said many a time, that is singularly responsible for dweebish, awkward, smart and funny guys getting laid. A thoroughly enjoyable hour and half of terrific intelligent writing by a master of the craft. Rent it, buy it, give it as a gift.
