It's pretty funny all the idiots who don't understand the difference between being in a dark room looking AT a bright light source is not the same as being in a dark room with a bright light source BEHIND you.
The Aurora shooter could easily see the crown, they were illuminated for him. The crowd could not, they were night blind from staring at a bright light source.
Idiotic pictures of a semi-darkened threatre without the projection system running are just that, idiotic. They in no way represent the conditions the victims faced.
It's not like this is an uncommon experience. Go to a damn theater. Then, while the movie is playing, look around and see how piss poor your vision is.
Then, for the full effect, bring some pepper spray and give yourself a dose and see how good your vision is while night blind and tearing up profusely.
