One of the finest sci fi movies ever made in my humble opinion. The underwater scenes were all fantastically done. The hurricane and crane scene as mentioned was great, also one of the best movie chase scenes ever done was probably the duel of the two subs. The stakes were high so it made the chase just intense.
Visuals still hold up. The soundtrack was great, especially the scene at the end with Bud meeting the aliens.
Harris, Biehn, Mastrantonio were all fantastic in this. The dialogue/chemistry between Bud and Lindsey worked really well.
Also plenty of subtle references to childbirth, like Bud is reborn again through the ship, umbilical cords like the crane connected to the rig then it gets cut, people are connected by ropes in the submarine search and the rig as well.
A+
