For the life of me, I CANNOT recall the name of this show, only the pilot episode and premise. A teenager watches his scientist Uncle attempt to use a roughly SUV sized vehicle to bore to the center of the earth through a volcano. However, the test seems to fail and he disappears. Years later, the boy, now grown, designs a massive version of the ship and, with either governmental or corporate backing, puts together a team of people [3 guys, 2 girls, plus himself, I think] who board the ship and use it to get to the earth's core, discovering a whole hidden world underneath.
There seems to be a deformed villain and odd creatures in this pilot. Also, the young man holds onto his Uncle's ring as a keep sake. It had similar special effects to Sea Quest: DSV but came out perhaps 3 or more years before.
Any idea what this was?
