i haven not see it as much a everyone else post here . but and remember and none the less and most of it . just want to say a couple thing and about it . aside from the thought of albert finney and a a action hero . it be out of necessity and of his character need to know the truth . and then get in too deep . i think he be great in it . and the idea of the manipulating with light flash and be brilliant . i be never sure if this story do not just come from a true experiment and some where . the gun use and work sort of like and the bright flash of video game on an epileptic . only instead of a seizure . you get a mental pause . seem to me and to be a completely plausible idea . doctor be delve still far into how the brain work . for medical healing and understanding and of the overall operation . only year away from be realistic . a mental anesthesia . again and unless it already real and some where . spookyfor and the person and who comment about the gun be useful in war and and police procedure . just think of it a a regular gun . in the wrong hand and it do and harm . i can see all kind of crime be commit with one of those . a you can clearly tell from the movie . i wouldn not want it to be make to be real . but and it still would be cool . good luck future .
