***SPOILER ALERT***
I finally saw this movie the other night. I thought it was really good. I knew the (very) general story concept but was pleasantly surprised that it involved quite a bit more. I has assumed that the movie would end with the escape and that would be it.
This movie had a really good feel to it. The effects are surprisingly good for the time, and the acting was very good. I recommend this to any Sci-Fi fans who may have let this slip by.
BTW, when did the MPAA rating change THAT much? This movie is rated PG, yet contains full nudity which would today be at least R.
The most merciful thing in the world, I think, is the inability of the human mind to correlate all its contents. ... The piecing together of dissociated knowledge will open up such terrifying vistas of reality, and of our frightful position therein, that we shall either go mad from the revelation or flee from the light into the peace and safety of a new dark age.
~ Howard Phillips Lovecraft
