The story is known. From sunrise to sunset of a late summer day, four young women kill their time in a deserted beach. They are saying corny (let God make them) jokes, sing discordant songs, recite reams of non-sense together, talk a lot about Woody Allen, managing to say absolutely nothing (which is a feat by itself). They tear up and laugh by themselves, they put up sunscreen, dive into the sea from time to time and create pointless fictions about the only house overlooking the beach. I believe i am getting understood.
But wait a minute! There is suspense also. A car is there and they are probably being watched, but may be not. Probably there is something else going on also, and if this can't be deciphered from the movie, then there are those courteous cinema "critics" who point it out in their "critiques", so that the viewers will expect it and not leave in the middle of the movie. Of course, at the end of the film, even this "something else" is unclear whether it is happening or not. The emotions that the director probably aimed to are lost and sunk in the general boredom that he has successfully generated thus far. The viewer can't take seriously this new discovery, when the director is not taking it seriously himself. There are some Latin American movies that use the technique of the last minute revelation very skillfully and the director should probably want to go and look them over.
However, this movie has a real achievement at its disposal: 14 hours of cinema time are condensed into 2 hours of real time, but the viewer is sure that it is rather 24 hours that have passed by. Since it seems that the director/script writer likes cinema jokes, he should have called his movie "The Big Sleep" instead of "Winona".
This is a typical example of bad Greek cinema that is promoted by certain critics. It reminded me of "Blackout" (1998), that had also been promoted at its time by certain critics. However, "Blackout" had been, even unintentionally, amusing in its pompousness. "Winona" is unable to even offer this shallow compensation for the the two hours waste.
