I saw this documentary at a pre-release event in Copenhagen with introduction speech by Niels Christian Frederiksen who is a reporter at TV2 Sport. Niels did a brilliant intro with very funny anecdotes, and there is no doubt that he knows a lot about Maradona and south American football in general.
The movie itself is pretty lousy from a technical point of view. Mainly it is a series of interviews and other meetings between the director(Emir Kusturica) and Diego Armando Maradona.
We get absurdly naive and ridiculous socialistic political comments from both the star himself and the director. We get a glimpse of Diego's poor childhood and his very promising beginning as a soccer player. We get lots of brilliant goals from his career, and we see the hysterical insanity when Diego revisits Napoli. Also we see touching moments with his family, and there is talk about his many years as a cocaine user.
The best parts are with the church of Maradona in Buenos Aires that is simply hilarious and über funny, and we get a fantastic live music gig with Diego on the microphone singing a fan song about himself.
A weird thing is that the movie was supposed to include some nasty comments said about Pelé, but they never appeared in the version we saw. So I guess the censorship thinks it is okay to call the entire western world and named politicians for bastards, but you can't say the same thing about Pelé in a movie?
All in all we get a good view from behind the scenes of the best football player the world has ever seen. He has never been the brightest man on the planet, but he certainly knew how to handle the ball and to many people he is still considered a God.
