Back when I owned the shadow I was warned not to watch the movie because it was so bad it would ruin the pin so I stayed away.
I had already seen The Shadow prior to owning the pin, and I actually enjoyed the movie. You do need to remember it was made a long time ago, but I also enjoyed Waterworld so maybe its me........
I got the missus to watch it once we got the pin and she understood the modes, callouts and the pin in general much better.
I think it is worthwhile seeing the movie/tv if you have not seen it. In saying that I have tried to watch the Twilight Zone series and I am struggling.....
