Of course this is a Roland Emmerich film --the man who brought us 'Independence Day' and '2012', but he manages to pull off a non-egotistical film (slightly! There's one name drop / plug about 'Independence Day' during the film but it's context-suitable). He's mastering the techniques of the classic 1970's disaster films such as 'The Towering Inferno' and 'The Poseidon Adventure' by being able to deftly merge character development with explosions and assorted necessary special effects. Script-wise, the whole thing feels like a no-brainer. It's very informative (the script, highlights are the real-life facts given about the White House by a comedy-relief tour guide), and brief. Nothing feels excessive here (dialog wise). Another highlight of the film is the performance by classic character actor James Woods as the mastermind behind the attack on our nation's 'Presidential Palace'. He emotes damn well and his rage as a disgruntled American comes through quite effectively.
All in all a good way to spend a late night / early morning! Can't wait for the next Emmerich disaster adventure tale I must say.
