“Alias” on Sunday nights has been a boon for ABC. After finally catching up on the episodes I’ve taped, I think I can offer some comments of my own now. After the 11/2/03 episode, I’ve noticed this: “Alias” is taking some lessons from every great soap opera, science fiction television show (such as Star Trek) , and previous spy drama: “Alias” is also finding aways so that no one (not a major character anyway) gets to die. CIA agent Sydney Bristow loses two years of her life, after having been almost killed in last season’s season finale. Sydney has no memory of what she did or where she went. Evil Francie, aka enemy agent Allison Doren in the physical form of Sydney’s late best friend Good Francie, still has some explainin’ to do. And the tension between Sydney, her ex-handler/ex-boyfriend Michael Vaughn, and his new wife/NSC agent Lauren Reed, is so thick that you’d need a power saw to cut through it. The third season of “Alias” isn’t nearly as plot-twisted as seasons 1 and 2, and I miss Lena Olin as Sydney’s morally-ambiguous mother (she and actor Victor Garber, as Sydney’s CIA agent dad) sizzled on the screen. But, “Alias” continues to be fun tv.
