What Alias did best was mix its outlandish plotlines with accessible characters who were more than just pieces on an espionage game board. The final season did have a few false starts, as it juggled the departure (and reappearance) of established characters and the introduction of new ones, but by the time it had reached its 100th episode, "There's Only One Sydney Bristow," battle lines were drawn as the core characters hurtled toward the show's conclusion. Not to be too cryptic, but the less you know the better, as part of the fun is puzzling out who's doing what to whom; suffice it to say that the ever-capable Garner, along with Victor Garber and Ron Rifkin as the dueling father figures in her life, laid a groundwork of personal drama that held the show together amidst all the shootouts, tech gadgets and costume changes. While (literally) everyone from Sydney's past made an appearance in the show's 100th episode (including an outstanding turn by Bradley Cooper as Syd's erstwhile friend Will), there were a couple great additions too: Rachel Nichols made a fetching Syd-in-training while Amy Acker, who played the daffy good-girl Fred on Angel, was a menacing and captivating adversary. We will answer one question for die-hard Alias fans: Yes, Lena Olin does return as the lethal Irina Derevko. Sorry, we're sworn from saying anything more. --Mark Englehart
