Jeez !!! WHY ... did they have to ruin the ending ??? :-(((((((((((
I loved the film so much during the first 3/4 of the film. It was mysterious, psychological and reminded me a lot of "The Shining" (which I actually didn't really like, but somehow it managed to capture the same atmosphere without suffering from the same drawbacks as The Shining).
But then, the last quarter came ... and my rating dropped down from 9 to 6.
4 things completely ruined it for me:
(1) Dr. Susan Wheeler's car doesn't start, someone across the street very obviously looks at her for 10+ seconds, then someone tries to catch the tube she was in and looks at her before and after his attempt ...
... ok this can all be coincidences, but at least when she nearly got herself killed by the man armed with a gun, who followed her through the hospital, she would know that she is in real danger, not only an imagined danger.
So why the hell doesn't she go to the cops?
(2) ... no, instead she returns in lion's den, by going to this Jefferson clinic.
(3) When she is to be operated by the evil hospital director, the boyfriend of Dr. Susan Wheeler (Michael Douglas) finally realizes that her life is in danger (when he hears him insisting he needs OP room #8), BUT doesn't try to stop the OP. It's his partner/girlfriend for christ's sake. Instead he runs to find the carbon monoxide bottle which ...
(a) ... he might not be able to find in time (and indeed, it was a close call: remember how she coughed and almost didn't wake up after OP?)
(b) ... he might bot be able to find at all
(c) ... even if found doesn't necessary solve the problem. An evil doctor still has ways to harm or kill your wife on the OP table (some of which might be hard to prove). Would you do the same with your wife ???
(4) Dr. Susan Wheeler repeatedly says NO, she doesn't want to be operated. And unless you are underage or put under tutelage it is a crime if you are forced to an OP. The nurses (who clearly were NOT in the know about the scheme to kill her) should never have proceeded against her will.
This is really not realistic at all. I would have added a fifth point, which was annoying. That's Michael Douglas not believing his girlfriend and treating her as paranoid (why does he go out with her then?). But I gave the film a pass on that one, because people like that do exist in the real world (unfortunately so).
I know that the film needed 1-4 for dramatic effects and to go along with the story, but that's a weak excuse. A good writer finds better ways to create tension without resorting to completely unrealistic scenarios (which actually harm the tension/excitement, because the viewer is taken aback "WTF?" and start's saying "well, it's just a stupid film" whereas prior to that I was forgetting that it's a film, which is the point of good films).
• solutions for 1+2:
(A) Susan goes to the cops, but their actions are insufficient for Susan, so she tries to do things on her own
(B) Susan does not go to the cops, but at least the film explains to the viewers WHY she doesn't do so
• solution for 4:
just don't do it. e.g. Susan is too tired to say "no"
• solutions for 3:
The OP has already begun when Michael Douglas learns about the OP and he is in a part of the hospital which is actually closer to where the bottle is, so he would think that his only chance is to run to the (nearer) bottle and he wouldn't have the time to reach the OP room (farther away). Plus when the OP has already begun, it is difficult to force it being stopped (someone has to finish the OP) and it could lead to a dangerous medical situation if there is a fight or whatever, so that would be in favour of searching the bottle instead.
