I, too, am in complete disagreement with virtually every word of the main review, and in complete agreement with the words of Mr Ebert.
The film itself is a masterpiece which had me in tears for hours - John Williams' sensitive and deeply emotional score is absolutely perfect in every respect. Like Star Wars and Indiana Jones, Artificial Intelligence and its score are one - Williams has completely redeemed himself in my eyes after suffering something of a creative snooze for a decade or so - in my eyes, anyway.
Might I respectfully suggest to anybody who was not profoundly moved by the film, and/or indeed its gorgeous soundtrack, that you put your hand where your heart is meant to be, and check that it is still ticking?
Films and scores like this do not come around every day. Not even every year. Not even every ten years. Treasure them.
