I am not sure why this episode was made. Most of this season seemed important, or adventurous, or entertaining. But for some reason we get this episode that was nearly unbearable to watch.
It was unique in the main characters were Carter, Mckay and Kellar. Their characters are all similar, brains over brawns. But even with 3 of the most intelligent people of 2 Galaxies could not figure out how to get out of this stupid hole!
That's right, this hole was stupid. An old mining facility was building about 8 inches below the surface, and somehow it managed to get a small sink hole after years of being abondond. This episode was filled with silly unsuccessful attempts to climb 50 feet.
