Highly suggest not to watch this film 'TV' if not mentally mature enough , the film create quite realistic simulation with the steps how they prevent from terrorism if such touch wood incident happened , London suppose a Lovely and chill ful City , while these kind of wars still going on , just wasting the time and money for study and Living, every time passing around P Square, the feeling really obvious, uncomfortable actually , I don't want to vote , the scored means nothing , just 4 'fill in the blank' <br /><br />Only Safty and Positive thinking cities encourage better Economy and investors to keep investing Time,Energies and Money
