I won't spend much time describing Alias, since most readers are probably already familiar. The premise is intriguing and fairly original, but the execution is too often calculated. It's obvious that some elements are specifically marketed to draw male viewers, while other are intended to appeal to females.
The two basic elements that are meant to appeal to males are the action sequences and Jennifer Garner's sex appeal. Both are too often forced. Even though the action sequences sometimes feel artificial, they're usually creative enough to compensate for this flaw. Almost every episode finds a reason to put Sydney (Garner) into a lingerie, bikini, or some other revealing outfit to show off her admittedly stunning beauty. While her physical beauty is striking, this cheap marketing ploy diminishes the show's emotional substance.
