The main theme of the series explores Sydney's obligation to conceal her true career from her friends and family, even as she assumes multiple aliases to carry out her missions. These themes are most prevalent in the first two seasons of the show.
A major plotline of the series was the search for and recovery of artifacts created by Milo Rambaldi, a Renaissance-era character with similarities to both Leonardo da Vinci and Nostradamus. This plot and some technologies used in the series place Alias into the genre of science fiction. Alias is the story of some pretty-faced college student who is recruited by the CIA to run off on her little spy missions (a pale rehash of just about everything ever filmed on the subject of espionage). The real CIA should be ashamed of this portrayal of their work. It appears that everyone on this series, ESPECIALLY Jennifer Garner, have matriculated at the Block of Wood School of Acting. The fact that THIS has been beating The X-Files in the ratings this season is a valid argument in favor of devolution.
Fortunately, it doesn't seem to be beating The X-Files by too much, so maybe this won't last too much longer. Although Alias may not be correct in everything it displays, what TV show is? It has everything a good series should have; action, romance, and characters that aren't idiots. Each character delivers something new and different to the screen.
The plot is always moving and it's hard to tell where it's going, so when you arrive. It's a complete surprise! With unending twists and turns, never knowing good characters from bad, the viewer simply falls into the plot and feels like they, instead of Sydney, are the main character. The only thing bad to say about the series is it sometimes takes a bit too much time to get into the plot- especially at the beginning of season 1. But, continue in and you'll find a series worth watching, a series worth buying and collecting. This show looks great, stylish, fast paced. Like popular shows like x-files or 24.
