The hacking scenes in most movies are atrocious. Remember that movie Hackers back in the 90's? There's a few scenes where they hack into a supercomputer using (at best) 28.8bps modems on Mac laptops and they're presented with GUI's that represent them graphically flying through a filesystem while searching for some files.

It's like tangue says, geeks in front of a shell just wouldn't be sexy enough.
