It is an incredibly slow paced film, and I think you have to be in exactly the right kind of focused mood to watch it and really be absorbed. I was lucky, I happened to be ready for immersing myself in something like that... a lot of the time I get distracted before a movie even starts and i'm only half watching
If you can't be bothered to watch the whole thing, or for anyone's reference who hasn't seen the film, here is the above mentioned scene... It's a fine example of Shannon's acting.
Perfect transition from menacing lunatic to vulnerable family man in a matter of seconds.
Superman: Don't be afraid.
Lois: I'm not. Helicopters, danger, go, go, go! Then we'll talk.
