These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Also has built-in Mood Whiplash when combined with the original intro video.
Idiot Plot: Jim Boumgarten. This segment revolves around a man who has a doppelganger living in the same city. He keeps getting mistaken by his townspeople for this "twin." Jim wants to know who this person is, so he decides to go on national TV to get to the bottom of this curious mystery...instead of just asking one of his neighbors who they were mistaking him for. It is still debated as to whether this was a gag segment.
Just Here for Godzilla: Many viewers, especially the younger ones, watched the show almost solely for its segments on the Unexplained, which were strange and fascinating enough to lead directly into...
The originally-aired, non-symphonic version of the song had some subtle differences...that might have made it even creepier.
The ending credits music was also extremely haunting. Every single thing about the show's music was awesome, really.
Most Wonderful Sound: Anytime Robert Stack said "Update!" It usually meant that a mystery had been solved, or at the very least there was a good strong clue.
Unless of course, the resolution was a sad one—that a missing person had been found dead, or worse yet, was still missing.
Replacement Scrappy: Then again, Robert Stack died on 2003. It's not like he can come back and take over, can he?
They Changed It, Now It Sucks: The move to the Lifetime Network meant that nearly all of the scary/awesome paranormal segments were booted off to make room for more "missing loved ones" segments instead. Yup: say goodbye to Bigfoot, UFOs and ghosts and say hello to more women crying and hugging!
A straight version would be a story of two girls who grew up in the same 1950s neighborhood and were close like sisters until one of the girls moved away with her family. Years later, it is discovered that the girls were sisters, but the one sister still continues to search for her long-lost sister.
Values Dissonance: It may be a little jarring to viewers when cases that involve people growing marijuana are treated with the same level of horror by the show as criminals that commit murder, rape, robbery, etc.
A large number of the stories about adopted children looking for their parents always mention how they kid was often abandoned by their young mother. While being a single teen mother isn't ideal nowadays, it's not exactly "abandon your child" horrible.
