These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Rooting for the Empire: Some viewers feel at least a little sympathy for Radek desperately fleeing for his life while being machine gunned by faceless guards. The fact that we don't actually see what his crimes are helps it.
It is mentioned at the beginning that the President had been to the Red Cross camps and seen the thousands hurt under his rule.
Special Effects Failure: The computer animation used for depicting Air Force One hitting the water was dated at the time and has not aged well over the years.
Tear Jerker: Most notably when the President is given a Sadistic Choice between the life of an innocent woman and his chance of saving everyone else. Ivan turns on the intercom so everyone on the plane can hear her plead for her life, right up until he shoots her, and we see the other hostages either close to breaking down or openly sobbing.
What an Idiot: Terrorist Sergei apparently doesn't know what explosive decompression is. To get through a locked door he jams a fire extinguisher in the handle and shoots it. On a plane. This results in at least five people (including a restrained terrorist) getting sucked out of the plane (although we see three people have chutes safely opened). And the President almost fell out. Unfortunately, Sergei isn't one of them. This also leads to the explosion of the tanker plane that was refueling Air Force One at the time, and could easily have killed EVERYONE if not for the pilot's quick thinking.
