“Fringe” started slowly on Fox last season, then gained steam (and followers) to become a compelling thrill ride. Those of us who’d already bailed by that time can catch up, in advance of the Sept. 17 Season 2 premiere, with the first-season box set, now out on DVD and Blu-ray. In the story, Anna Torv, Joshua Jackson and John Noble team up to investigate a series of mysterious events (”the pattern”) and conclude that someone is using Earth as a lab to experiment with everything from astral projection to reanimation. Oh, and there’s a cow. The DVD set includes looks at the real science of “Fringe,” a featurette on special effects and interviews with stars and producers, plus much more.
