Rather than attempting a review it would be best suited to attempt in bringing out what Woody Allen tried doing. 'Relationships' has been something disseminated and analyzed by thinkers for a long time. It might have been probably because this complex entity is present only in humankind. Allen tries to probe this complex equation his own light hearted way.
Allen plays a stand up comedian, Alvy Singer. Diane Keaton plays Annie Hall. Both the protagonists have their own problems and issues from childhood, family and relationships. The treatment is light hearted and humorous. Woody is in no hurry to offer any solution and he doesn't seek any easy way out.
Alvy and Annie have troubles of their own in respective relationships. They meet each other and things start off very well. There is a hope of fruition. But slowly the weaknesses comes to the fore. Still they carry on despite the inherent weaknesses. Ultimately the relationship wilts away inspite of pretension and dullness.
Overall this is a beautiful movie which deals with so many complex terms in its own simple way. The movie ends up with a story from Allen
A man goes to a psychiatrist, ' Doctor, my brother is crazy. He thinks he is a goose'
'Then bring him to me'
'Wait, let me get his eggs first'
Relations are something like that. No matter how absurd and insipid it is we want its eggs!
