Infuriating

I don't understand how you think that Sandra Bullock didn't mature and gain character and integrity in the movie. Despite her extreme fear and moments of panic, she keep struggling to learn and, so, to survive.

Dr. Arthur Carrington, in The Thing From Another World, got it wrong on all accounts. He wanted to allow a horrible being presumably on a horrible mission, to live so that he could learn from it. Someone asked him, "What can we learn from that thing except a quicker way to die?"

So sacred (and, now, we can see how dangerous that kind of knowledge can be) was science to him, he said, "We owe it to the brain of our species to stand here and die... without destroying a source of wisdom." There is the argument, of course, that Carrington mistook knowledge for wisdom, a very dangerous misunderstanding. In fact, he also said that The Thing was superior because, among other things, it lacked emotion.

You point out that Dr. Ryan used extreme emotion in her way to convey how terrified she was. Yet, Dr. Ryan Stone uses knowledge and wisdom and experience to live. Terrified, alone, knowing she had failed at attempting to fly space craft before (she had "crashed" every time she had been in the training simulator), she goes forward to succeed.

I guess the question we could ask ourselves is, "in the same situation, would you or I spend some time screaming and crying"?

I do admire your ability to immerse yourself in the movie and at the same time put your thought bubbles onto the board.

"I've basically watched a featurelength display of Sandra Bullock gasping and being stupid in space"

The most asinine of her list of crimes and misdemeanours being to totally ignore the sparking electrical contacts when she entered the space station; novice or not I cannot believe that the ingrained fear of fire on board a space vehicle was not deeply instilled during her training. There's even a reference to NASA's dread of fire in the movie "The Martian" - a fear which meant that a crew-member's wooden crucifix was the only kindling available for the eponymous hero's project.

I can make allowances for the fact that she is not a professional astronaut and was operating under great stress, but to ignore the astronauts' most feared (non-external) danger is something I cannot accept.

"You've got lovely eyes Dee-Dee, never noticed them before, are they real?"

I suggest you don't make typos in posts where you are calling other people out on grammar. It makes you look both stupid and hypocritical.
Looking at your posting history makes it obvious that you are just an internet troll, but mistakes like this makes you a failure even at that, so you have my sympathies.
Both for the failure and the acute need to get a life.

I suggest you lean basic grammar

That is completely irrelevant to the argument of her character's intelligence.
A stupid character is just as stupid regardless of how immersive the movie is.

Immersion wasn't my complaint; her stupidity - and so, in turn, the logic of the script were.

Effects were good,and it worked as a piece of escapism,but when she emerged into the water I for some reason expected to see a shark start to circle.
