Everybody’s got an adorable parallel-universe nickname — The Walternate! Flauxlivia! Pacey! — on the always unpredictable Fox sci-fi show Fringe. Sure, it’s no Lost (nor X-Files, nor “Enemy Within”) but it’s got its charms, including high-speed pregnancy, Leonard Nimoy impressions and cast members from “The Wire” not being given enough interesting things to do. Host Jason Snell with Dan Moren and John Siracusa.
