There's no escaping the fact that this film is unadulterated rubbish in which, as the Earth literally starts to crack, the lead heroine ignored her responsibilities and diverts helicopters and military resources to go chasing after her husband and daughter.
One clue to the paltry budget for this movie is the fact that the name of the company in charge of CGI is 'Tiny Juggernaut'. If, indeed, the budget was as low as I suspect (a fact clearly implied in the the 'Making of' extra feature), then perhaps 'Megafault' is actually a quite reasonable achievement.
But, in the end, there is not a lot to recommend it. There are endless shots of the faultine racing across cities and landscapes (exactly as in the multi hundred million dollar film '2012') and equally endless shots of panic and haphazard explosions (exactly as in the multi hundred million dollar film '2012'). The end of the story resolves with the fault being halted and the split-up family being reunited literally on the brink of disaster (exactly as in the multi hundred million dollar film '2012').
Do you get my drift? (An intended tectonic pun there) .....
This film was made on a shoestring and yet in almost all respects it matches the incredibly similar, over-hyped and budget-squandering movie '2012'.
5 stars? - definitely not.
1 star? -- that would be mean in light of the comparison.
3 stars? - justified, I think. Just don't expect anything much above the level of rubbish.
