Chain reaction

Analysis:
We've a scientific research here vs business in dirty way, science vs money with any price, Keanu and Rudall and others represents the noble science spirit, Brian Cox represents the business and dirty level, anything can be with any price, evil but not wise, Morgan Freeman represents the dirty job too but a power in the country, can be evil but wise, he's like a part of a secret level in government, the level that is high over than the normal citizens understanding, for that they can do dirty works but in general for the general benefit of the nation, not like Brian Cox model, they can use someone like Brian Cox but they don't leave someone like this to be really so powerful in government, but he can be some powerful, he used the power with no necessary, his management to the situation the evil and unwise. I liked Morgan Freeman position in the movie, you can't judge him as an evil one 100%, it's like we've to do some evil in some situations, like a kind of justifying but not absolute one. For Keanu, he can't understand this kind of ideology Morgan have or high level in government can work with, he's normal citizen who want to feel safe in his country, for that the FBI agents in movie are of appropriate kind for Keanu when they understood that he's innocent, he can't imagine another secret dark level in his country or he feel no safe living in his country. FBI agents seemed as ignorants in the beginning of the movie, and through the movie their opinion changed about Keanu, but with the sense of normal citizens not a high agents in government those lean on good oil and calculation, mentality, so FBI agents in the movie are of the simple kind, those who have simple understanding like the other normal citizens in the country.
I think Brian Cox represented too the extreme form of capitalism ideology, Morgan Freeman represented kind of liberalism, FBI agents thought with simple socialistic way in some scenes vs Morgan Freeman.
