some of his finest work in this film does

To be sure, some of the shortcomings of "Phantom Menace" (1999) and "Attack of the Clones" (2002) are still in evidence, and Mr. Lucas's indifference to two fairly important aspects of moviemaking - acting and writing - is remarkable. Hayden Christensen plays Anakin Skywalker's descent into evil as a series of petulant bad moods. Natalie Portman, as Senator (formerly Queen) Padmé Amidala, to whom Anakin is secretly married, does not have the range to reconcile the complicated and conflicting demands of love and political leadership. Even the more assured performers - Samuel L. Jackson as the Jedi master Mace Windu, Ewan McGregor as Obi-Wan Kenobi, Jimmy Smits as Senator Bail Organa (note the surname) - are constrained by their obligation to speechify. Mr. Lucas, who wrote the script (reportedly with the uncredited assistance of Tom Stoppard), is not one to imply a theme if he can stuff it into a character's mouth. Ian McDiarmid, as Supreme Chancellor Palpatine, who transforms from a rancid political hack into a ruthless totalitarian before our eyes, gives the most powerful performance; Yoda, the spry green Jedi master voiced by Frank Oz, some of his finest work in this film does.
