Otherworld had enormous problems.

First of all the concept sucked. What worked for Edgar Rice Burroughs in 1910 or the nitwits who brought us "Land of the Lost" doesn't work for a modern audience geared up for serious science fiction. Pyramid transportation to an alter Earth? Lost me at the gate and goes downhill from there.
Also I don't buy into a Rift Earth universe.
The technology was laughable and the artificial social constructs (called plot contrivance4) top drive story made no sense.
in a big way.
