This is every airport, earthquake and inferno flick rolled into one, only not as good. A movie could be made about all of the technical impossibilities and another about the impractabilities contained in the over two hour visual earache that was this saga.
At least it had political correctness, Biblical allusion and black and white moral preachiness going for it.
My kids liked it and I didn't spoil it for them with my opinions. My recommendation is drop your kids off at this one and see something else.
