Suppose you take a vehicle. It doesn’t matter what vehicle. It could be a car or plane. Now throw a fractured family into it trying to escape a crumbling planet. Suppose that the crumbling only happens like a wave where everything in front of the family vehicle stays intact while everything behind the vehicle totally collapses right behind the back wheels. The only exception being buildings that may fall in the path of the vehicle, but these buildings are of such poor construction that the family car can drive right through them. Of course, in this world, 2 flying lessons qualify you to fly a twin engine plane from take off to landing, taking evasive maneuvers and avoiding a stall, then graduating to being a co-pilot of the world’s largest jet. And in this world, similar to that of Star Trek, there is no language barrier. Everyone speaks English when needed. Also, introduce the conspiracy of the elite to build Ark’s to survive the pending doom. The elite guard their survival so much that they kill anyone that threatens their plot. This is also done at the sacrifice of 6 billion people as none of them are made aware. But, at the very last second at the most critical moment, the conscientious person convinces the captain of one ark to lower the security ramp to save a mere thousands or so of people, jeopardizing 3 years of planning. And back to fractured family. Since there hasn’t been any standard nuclear family portrayed in a catastrophe movie in 20 years (Armagedon, Independence Day, Knowing, The day the earth stood still……), let’s have hostile kids to their father who ends up winning their trust and affection in the end. And since Dad has been reinstated, you have to eliminate Mom’s boyfriend that you spent time getting to like so that Mom and Dad can get together in the end. Now, you have the plot to the very cheesy movie 2012.
