I remember seeing Otherworld as a little kid, and even then boggling at some of the loopholes in the writing. For those who don't know the concept, which is probably a lot of people, an all-american family is touring Egypt in the early 80's, on the day of a Total Solar Eclipse. A local boy offers them a special tour of the Great Pyramid, and they take him up on it, and lead them deep into the pyramid, before demanding more money. When they refuse, he puts out the light and runs away, abandoning them in the heart of the pyramid, right as the eclipse happens. The entire family is now teleported to mysterious otherworld.
This world is earthlike, but divided into distinct "zones", each one with a unique culture and style, and a string of obelisks running through the world leading to their capitol city. The obelisks have the "eye in the pyramid" insignia found on the US Dollar, and it's quickly implied that the leaders of this world in this distant capitol either came from Earth, or have a way of going to Earth, so the family sets out towards this capitol to find a way home, travelling through many unique "zones" and having a different adventure in each one. Fortunately the natives all look like humans and speak English.
The problem is that moments after arriving in world, they wander across a road where an electric patrol car comes by and a commander of the police/military forces of the world, the Zone Troopers steps out and tries to arrest them. They beat up the commander, steal a mysterious crystal he was carrying, and escape to the nearest town. It turns out that this crystal was an irreplaceable and unvoidable access device to the entire computer systems of the entire planet. It can change records, open any door, issue orders, void orders, access confidential files, and it lets them not worry about the bureaucracy of the world they have arrived in. It also gives them a recurring villain, as this commander pursues them to get his crystal back.
Okay, this all falls apart in one zone, when they are trying to live a normal life in a place much like contemporary America. The son fails a big exam in High School, and finds his locker cleaned out and a red tag in there, and finds out that means that because he failed that exam he has been drafted into the Zone Troopers and must report immediately for training. That's bad, what is worse is that enlistment in the Zone Troopers is for life. The dad at this point refuses to use the crystal to get him out of it, telling him about how they shouldn't use it to solve all their problems and he got himself into this problem by not studying enough at school. The son learns that if he excells at training, he can be a Zone Trooper Officer and be allowed to immediately resign, so the episode is about him trying hard at Zone Trooper training so he can escape.
They could only make it a few episodes before backpedalling on one of the core concepts of the show: that they have unlimited bureaucratic power within the world they are in, and it makes the normally loving and warm dad suddenly describable using words Eric's grandma wouldn't approve of.
