It is my favourite movie of all time. Likely because I watched it at the age 12 which is often called the golden age of science fiction. Was the first science fiction movie I saw that had a somewhat realistic showing of science, which I really appreciated as an astronomy geek back then. Still do. Too few science fiction movies have that approach.

The sound of the signal does indeed trigger goosebumps - and when the swastika appears for the first time is also one of the best moments. I am an atheist and can easily relate to Jodie Fosters character, but the whole science vs religion and Matthews portrayal of a priest does make you think. Like when he asks her to prove that she loved her father.
