This is such a rich and oily adventure, and it is a life-threatening adventure when it is too idle, and the poor are still honestly living for the sake of living.

Selfishness and panic are an explorer's nightmare. A very manly film, realistic and cruel. Cameron's 3D camera technology helped out, and the visual effects were addicting, perfectly restoring the magnificent scenery and deep water experience. The plot mode is very routine, but the mood can't help but fluctuate with the plot. In addition, the technical details of this film are handled very realistically.
