Off-world, Keller, Carter and McKay are trapped in a mine....with earthquakes happening all the time.
Refreshingly oddball episode that has more in common with The Poseidon Adventure (1972) than with anything science fiction related. I am told some viewers found this hour a bit empty, which is a valid point, but considering what came before with endless space battles and all the rest....I think Trio has a place here.
One of the big things that separates Star Trek from Stargate is that Stargate often references current and not so current Hollywood movie/TV stars....we get a lot of that in this hour. Small talk is common. But it is well played here so why not.
This is not the first time this series has done a show with two or three regular characters trapped somewhere, but I don't recall an hour with such a nice 1970s-disaster movie-feel...in fact I was just waiting for McKay to make an Irwin Allen ("The Master Of Disaster") joke, but it never happened.
If watching on DVD, watch the special feature on the making of this episode. What started out as a low budget episode turned out to be one of the most costly and complicated (to make) of the season!
