All really good films have a good start sequence like films like Cliffhanger or Vertical Limit and this film is no exception with a heart stopping sequence beneath a ship being sucked into its propellers which immediately grabs the viewers attention - well done to the director for paying attention to the rules of good movie making.

Add to that some utterly breathtaking photography and drone footage and it starts looking very good indeed.

Good acting and nice characterization, one character is focused, extremely intelligent and capable then we have the other one who obviously has problems , ruined her marriage and is a bit of nightmare and of course its the intelligent and capable one who becomes trapped and so the incompetent partner is the one who has to try everything (and mostly failing) to free her sister and save the day - it has all the things a good movie should have right from the off and it does not disappoint! As one reviewer has pointed out it is actually quite close to reality when you are diving so they clearly researched before they made the movie and having seen someone with a case of the spinal bends its quite disturbing and a completely horrifying experience even for people watching it happen to someone else as i did once so this film did bring back memories!

You have to laugh at the one star reviewers complaining about the dog scene or this and that would not happen in real life and the sister was stupid - Err yes that is why she was chosen to be the one not trapped under the rock as she was the incompetent dimwit of the two sisters - what didnt you get? When are people like this going to stop reviewing movies? If everyone did the logical and sensible thing then the movie would last 10 minutes and be over immediately - its what is called making a fictional movie guys - perhaps stick to dominoes if you cannot review a movie properly or dont understand the construction of a screenplay! It really does disappoint me to see low brow reviewers giving a good film like this a 1 or 2 star review which means its the worst film you have ever seen and which this is plainly not if you have ever seen the Bad Batch with Keanu Reeves - Go watch that and then tell me you still think this is a 1 or 2!

The only disappointment is that they went for the usual hollywood happy ending when they should have ended it with what would really have happened if someone had made so many ascents and descents without the safety breaks they should take to remove nitrogen from the blood then it would really have broken movie making rules and we need this to make movies that truly shine. Overall a good exciting 7/10 nights entertainment.

Now for certain things to happen, some mistakes or things have to happen. A certain amount of small things that lead to something bigger. Now not all of those things may seem plausible to all watching. You just have to suspend your disbelief and let the flow of the story and the characters take you on a journey and dive in.

Now I know that some didn't really like this and it is imperative to not have anything against movies taking mostly place underwater. The tension is there and the movie really builds that up nicely. I don't even want to know what the actors (and stunt persons) had to go through, including some of the crew of course. So if that amazes you and you can forgive some cliches and flaws the movie has, you are in for quite the ride ... dive!

Felt and went rockbottom at 20 phatoms below the sea surface. do you have any kind of cronic obstructive lungs issues, do have your oxygen at hand ,because youre automatically catching and holding your breath in this flick.

but its not the very best of die on a dive films ive seen through the years, but its intense though. the dynamics between the actors are so shallow and bad ,i would never have dove with any of then because daredevilism isnt my preference. and if all the signs from heaven had occured to me before my dive i wouldve called it a day long before dipping into the water. im not a certified diver, but have done a lot of diving as a freelancer in my younger days, though i still have my orange scubapro wetsuit .but all the dire straits these two women are up to could never have been foreseen or predicted.. if there are one bad thing about norway ,its darn desolate where they are diving and the phone signal basicly dead if turning round the mountain.

but to all viewers that doesnt understand the language, the 2 dames are swedish and not norwegian,that maybe the reason for all their bad luck and headless hunting for rescue. the wooden stick brought to the seabottom would actually have been a near impossible task to take down, just a little glitch among others.

but its a viewable film and im very squemish and grumpy and old man tonight so its just a 7 from me.
