He’s better than Benoit and he’s proved it.  Now, Kidman has the talent to be the leader in the future but he needs to get rid of the fleas and get experience against somebody but the Mexican’ts.

ONCE UPON A TIME IN MEXICO
A film review by Steve Rhodes
Copyright 2003 Steve Rhodes

RATING (0 TO ****):  * 1/2

Robert Rodriguez’s ONCE UPON A TIME IN MEXICO, a miserable excuse for a movie, is almost saved by Johnny Depp’s wonderfully hammy performance. Playing a three-armed CIA agent—don’t ask—who hires a hit man with a guitar gun, Depp is as good as the film he is in is bad.
 
As CIA Agent Sands, Depp gets to deliver some great dialog: “Sometimes a revolution is what is needed to clean up the system—one gigantic enema,” and “Are you a Mexican or a Mexican’t.”
