die hard 4.0 with lessons!

I watch die hard 4.0 yeasterday. It is awesome. Selling point is 'firesale'(virtual terrorism) and hacker. Just like transformer. Hacker is the main focus of the movie.
In the movie, virtual terrorism so called firesale (everything must go) .The attack focused on four primary objectives: disrupting transportation, stealing and destroying financial records, disabling all public utilities, and creating fear with a PSYOP media campaign. The attack is more traggic than 911. It not only involve life but involving bankruptcy of the government. After looking at the movie, it seems to me that using computer to control everything is not a good idea after all. I think human should be involve in controling and can be manually override everything if computer being hacked and situation in chaos. The action part is still good and packed. Selling point is a chaos created by firesale. The traffic, subway, biological attack, finance and psyop. I like the movies because that is progressive improvement in terrorism for the movie . Die hard 1 is fighting terrorism at building, die hard 2 is fighting terrorism in plane, die hard 3 is robbing the high-security vault in the basement of the Federal Reserve Bank of New York with the diversion of bombing New york. Die hard 4 is stealing money by create fire sales.
If that is 5 maybe fighting a biological warfare or cyborg?
My advice is watch the movies .Lesson is do not let computer control your life.
Actual facts is that is no John McClane in the world.
