Well worth a look.

I can't believe the amount of bad-mouthing this movie is getting from IMDb users. Do you not get the point of a Biopic? This is a fraction of the life of Ali, this is an insight into his life - it is not trying to give you an understanding of the man. Michael Mann is showing you what the guy did, and allowing you to make up your own mind whether you want to like him or not. why do you have to care about him? So he's a womaniser... so what? he's a boxer - the GREATEST boxer. the guy has flaws - like any other human being. thats what makes the movie so accessible, and so great - you see the man for who he is: his beliefs, his desires, his ambitions, his loves and his hates. Kudos to Will Smith for an Oscar-worthy performance, and for Mann who allows the film to show a man holding on to as many of his principals as he can - failing in some, succeeding in others.
Yes, it may be too long, and it will alienate some of the audience, but the audience who DOES get that a film doesnt ALWAYS need a plot which starts at A and ends at B with closure and a happy resolution, will enjoy this film for a its quality direction, performances and stronghold on the material to produce a great film.
