Seeing this film again, I was struck by how...
...depressing the film really is.
Seeing this film as a kid: Very entertaining, exciting and a fun movie.
Seeing this film again as an adult: Depressing seeing all those good people getting killed while finding themselves in such a horrible predicament. And the agony of William Holden's character for cutting corners. Still exciting, but it's a much more serious film when you watch it with mature eyes.
I was also impressed by all the actors putting themselves in the middle the action. All the fire and explosions. This type of practical and dangerous film making would not be done the same way today.
It's still a very good film, and deserves it's spot with The Poseidon Adventure as the best of 70's disaster flicks.
