Stand-up comic "Alvy" (Woody Allen) has a lively history with the women in his life. His marriages - of which there have been two - have all ended rather suddenly, as has his latest dalliance with the eponymous singer (Diane Keaton) who won't have sex with him unless she gets high first! Now this latest failure perplexes him. He thinks that over the years he would have managed to iron out the frailties in his character and so, by now, be able to retain the affections of a woman. What keeps going wrong? Woody Allen did pretty much everything on this production so is able to well focus the self-deprecating Jewish humour that threads through the feature as well as using the retrospective nature of the story telling to quite amusingly but also entirely plausibly assess not just "Alvy" but what scenarios from his life, loves, upbringing and choices helped mould the man into that rather flawed creature we now see before us. At times it is a little wordy, and he does recourse to in-jokes once or twice too many, but for the most part this is a confidently pitched double-hander with two actors who have an unique sort of on/off on-screen chemistry that makes this an engaging and enjoyable ninety minutes that might well ring true in many a bedroom.
