Fringe isn't widely regarded as a “scary” show, but you'd be hard-pressed to find a program with freakier visuals on the idiot box. The J.J. Abrams-backed science fiction drama trails an FBI agent (Anna Torv), an enigmatic boy genius (Joshua Jackson), and his nutty doctor of a father (John Noble) as they investigate paranormal and otherworldly happenings, all while working to keep a parallel dimension's evil version of Noble's character from bringing the apocalyptic ruckus.

It's a wide-open premise that allows Fringe to bless viewers with an assortment of strikingly bizarre imagery. Early into Season Two, for example, a shadow-man attacked a guy whose wife comes home to watch her husband disintegrate into ashes; “Marionette” (Season Three) features the pleasant shot of a mad scientist controlling his wife's dead body like a puppet with ropes and pulleys. And that's just a sample of Fringe's most heinous scenes, which once again begs the question: Why aren't you watching the show yet?
