别有洞天2001

    描绘洞穴探险、介绍嗜极端微生物研究的制药价值，是这部纪录片的主体内容。跟随摄影机的视角，可以看到壮丽的自然风景、体验紧张刺激的探穴过程，让人向往着有朝一日也能够象那些探险科学家一样，带着对一切的未知，向地球深处某个黑暗的虚无中勇敢前进。寻找刺激的渴望和对未知的探索也许是每个人心中隐藏的天性。
    还有一点要提，配乐相当不错，看过的人应该都有一个相同的感觉，爽的不只是眼睛。
    略显不足的是，可能是出于片长方面的考虑，全片只讲述了——格陵兰冰洞和墨西哥洞穴潜水——两个洞穴的探险。因为量不是很足，难免有点意犹未尽的感觉。

a very good documentary,introducing some scientists probe into the deep solution crevice in greenland and peninsula of Yucatan in mexico,very interesting and make me convulse in brain because the deep insides of these solution cavity are really beautiful,the water in these area are so pure and transparent.

i used to see some documentary produced by national geographic channel,talking about two guys diving and exploring the caves in Yucatan,but the definition of that documentary is not very high, comparing to the HDTV of this one.

when i watch this kind of movies, i will always regret that i choose humanities instead of science which make my orbit of life not very exciting.but "You can't make an omelette without breaking eggs",if i chose science as my major,maybe i would become so busy that i even didn`t have time to watch this documentary and then write this blog.
