In a theater probably closes to the door ( entrance ) off to the sides. If someone is shooting down isles, and your in the front, thats a higher chacne you will be hit(down range). Stay up field/range and off to the sides. We have two story seating so I just sit up top and watch the middle stair/entrance. When I eat out, I always face the front door.
