Very ambitious special effects
18 February 2017 | by (Tennessee) – See all my reviews

While looking for a missing scientist, Frank and Joe get more than they bargained for with a UFO that runs them off the road and an old house with growing rooms and disappearing floors. The boys also discover that someone else is looking for the scientist - a couple of Russian agents.

The Disappearing Floor is a good, fun episode. I remember when it first aired and how much I loved it. It's got a lot to offer with the UFO, creepy house, interesting mystery, and the sense of danger. But looking back at it today, you can easily see the episode's faults. It's a very ambitious episode for a show like The Hardy Boys / Nancy Drew Mysteries. By today's standards, the special effects are . . . well, they're weak. None of it looks at all realistic. But, I'll cut The Disappearing Floor some slack based on when it was released and what it tries to do and give it a 7/10.

One thing that has always puzzled me about The Hardy Boys / Nancy Drew Mysteries is all the sound looping or dubbing (whatever you call it). A lot of the dialogue sounds so unnatural and was obviously recorded later on in a studio. While it's hard not to notice in any of the episodes, it seemed especially apparent in this one. It can be distracting if you're not ready for it.
