Alert reader Marty suggests a “discussion about which episodes fans consider to be ‘graduate-level.’ I assume what he means by that are episodes that — either because the movie is painful or the host segments are impenetrable, or both — will drive newbies away screaming, will cause casual fans to wander into the kitchen for a snack and may even make seasoned fans look at their watches and wonder what else is on, but which hardcore MSTies just love.

Having just done “Monster A-Go Go” in this week’s episode guide and “Manos” only a few weeks away (both would have to be included in this list), it definitely seems like a timely topic. I once made the mistake of showing “Manos” to my sister as her very first episode. I guess I thought she could handle it. She couldn’t. Oh well. Lesson learned.

One I would pick is on the most recent set: “Last of the Wild Horses,” featuring a difficult black-and-white movie and host segments you would only really appreciate if you knew the show and the characters very well. But I just love it.

What’s your pick?
