I copy and paste >> snalen "snalen" - (another reviewer's commentary here) who expressed it perfectly. "snalen" said:
Jan Schlichtmann (Travolta) is a Boston tort lawyer and something of an ambulance chaser who is initially reluctant to take on an industrial pollution case involving some children dead of leukemia in rural New England. He changes his mind when he realizes the likely defendants are a couple of big companies with particularly deep pockets and smells the possibility of serious money. Over time, however his interest in the case becomes a moral obsession. The cynical becomes a crusader, refusing offers to settle as his company's finances spiral downwards towards bankruptcy.
If you like courtroom dramas, this is highly recommended. It's one of the best specimens of the genre to come out of America since `The Verdict'. It's interesting to compare it to `Erin Brockovich' released a couple of years later. EB is about how a heroic small timer takes on the big boys of corporate America and how her pluck and determination triumphs over all obstacles, something of a legal feelgood movie in other words. Which this, to its great credit, is not. Its central character, for starters, is far more amibivalently likeable: initially just out for a fast buck, moral seriousness has to creep up on him and take him by surprise (perhaps reminding writer/director Zaillian of Oskar Schindler whose story he scripted for Spielberg a few years earlier) and the story's development paints a significantly more ambivalent picture of what pluck and determination can accomplish. It's a highpoint of Travolta's acting career even if he is comprehensively upstaged by Robert Duvall, on brilliant form as his quietly cynical adversary, bigshot lawyer Jerome Facher who knows far better than to look for the truth in a courtroom...
And I add, a VERY entertaining and interesting movie with some redeeming social value, a very provacative movie that should inspire many 'thoughtful' viewers to an enlightened perspective ... that may not have ever been considered before!
