Meh - I'm a wuss; Option 1. I just don't get any real enjoyment out of jumping in my chair, or lying in bad after a movie with scenes going through my mind, unable to get to sleep...
On the other hand, commanding an APC through the streets of Jenin, with grenades and makeshift explosives going off on top and all around the vehicle, bullets pinging off the sides, etc etc... wasn't all that scary. Neither was disarming live mines in a hornet-ridden minefield, come to think of it.
*thinks back*
Scariest movies I've seen (to clarify, I haven;'t seen any of the Alien series, any Texas Chainsaw Massacre, nor The Ring, Others, or even Silence of the Lambs/Hannibal. I know - poor, deprived me. Bah.) was when I watched Event Horizon and Sphere back-to-back one boring saturday on base.
