We know, we know, another spy show. But Alias, starring a young Jennifer Garner, is indubitably a classic. (Side note: Can we talk about her hair?!) The series follows Garner as a young woman who discovers her family's ties to the CIA, and embarks on top-secret international missions for the organization, only to later discover she's not actually working for the CIA. Ooh, the early 2000s drama!
