Very very predictable, including the post credit scene !!!

Good movie, but best of all time? Hardly . . .

If the ambition is to provide two hours of instantly forgettable, popcorn-munching escapism, it succeeds.

It's the kind of movie you'll want to see a second time with someone who hasn't seen it yet, to remember what it was like to watch it for the first time.

For a movie with Charlton Heston, it is unusual bad. The camera work is an imposition. Many of the "underwater" scenes (like the falling rocks) are actually made ashore and you can see that way to obvious. Special effects are cheap. The plot is unreliable. Whenever the "DSRV" connected to the submarine and they opened the hatch, there wasn't even one drop of water coming down. The story is unnecessarily stretched to the point it hurts. At least in the last half hour it gets a bit better. The overall acting sways between weak and average. It's the first movie I had to give a bad rating and it was a disappointment.I normally enjoy movies with Charlton Heston. In this one it was really hard to just sit about one and a half hours and watch it till the end. But you can't judge a movie when you haven't seen it all.My suggestion is: skip this one.

A better-than-average disaster movie, due mostly to the absence of any ridiculous scenes. (There are no overweight older Jewish women who won swimming medals many years ago trying to reach the sub, for example.)On the other hand, Ronnie Cox as the first officer goes to pieces very quickly and you wonder why the Navy ever thought he'd be able to command a sub of his own. Also, you've got to ponder the initial collision. The sub's crew basically just lets a freighter in open water run them down, not even noticing that the freighter is in the area until it's too late to do anything about it. Kind of makes you wonder.Heston is restrained in his role, which works out pretty well. Everybody else does a good job (except for Cox) and the special FX are average for the time.Definitely worth watching.

This is a great movie for military enthusiasts and disaster buffs both. If you're looking for that, this is a classic.Don't pay attention to reviews about military-based films by anyone who derides the movie as a "waterlogged Naval documentary," which contains two errors in one statement. First, there is no need to capitalize "naval," and second, what kind of snobby theater twit attacks a movie for being too "Naval" when the subject is about...a U.S. NAVY SUBMARINE? Next he'll attack Ghostbusters for being a shill for paranormal investigators.Stupid reviewers aside, this is a good movie.

"Gray Lady Down", which bears very little resemblance to the novel it was based on, is a nice, entertaining action thriller that holds up well today in contrast to today's action films because it's cloaked with a realism and plausibility that today's filmmakers seem determined to avoid like the plague.
