TMS produced this late 90's Canadian adaptation of an Argentinian comic and it shows. The silky smooth action animation rivals that of Batman TAS of the same period and this is the series' best aspect. Every episode features at least one elaborately staged and beautifully shot action set piece which would have been insanely complex and expensive to shoot live action. The look of the series is an odd mix of comic strip art - hairy arms are depicted as dark dashes! - with extraordinarily detailed backdrops. The city setting is a marvel in itself, a blend of the old world with its dilapidated opera house, narrow streets and open air market stalls and mad science cybernetic modern. A character appears to be strolling through MGM Paris of the 1930's only to run across a killer robot.
The stories never get quite as complex as the best of Batman TAS, but they are consistently well-plotted and watchable. Suspense abounds and there are some frightening moments, but no excessive violence amid the often wild action. The characters are a bit superficial and their interactions can be a bit simplistic but even this aspect of the show exceeds typical teen cartoon standards. The series' major theme is a positive one for young viewers, that even something created for bad purposes (such as the main character herself, a bio-cybernetic construct) is not inherently irredeemable. All shows should be this humane in this age of dark and gritty superheroics.
