3. Thriller (Seasons 1-2)

Category: Classic TV Shows
Stars: Boris Karloff

Discussions centered around classic television anthology shows usually focus on The Twilight Zone and Alfred Hitchcock Presents, two examples of the format that regularly genre-hopped from all-out horror to more thriller-based drama. One such program that's too often forgotten, though, is Thriller, the Boris Karloff-hosted cult classic that concerned itself solely with terror; in that regard, it's the best purebred horror anthology series ever made, a 67-episode exploration of murder, the supernatural, and unhappy endings.
