Unknown World

I thought that this would be a typical "lost world" type movie. A bunch of people set out on an adventure to find a hide away from the threat of nuclear war by drilling deep into the earth...sounds similar to a lot of other story lines. Problem is that with effects of this style (not too bad for the time), and acting this bad, I thought at least we would get a cave man or a cheap dinosaur. No, they just keep going deeper and deeper, losing members of the team as they go. It also ends so abruptly that you think the writer just gave up.
