This may not be the worst film I have ever seen, but I cannot recall anything more dreadful at the moment. The script was apparently written by folks unfamiliar with seismology, powered flight or the US military. Unfortunately the film is largely about seismology, helicopter flight and military operations. The dialog is bad. Even a veteran cast couldn't make me accept this simplistic chatter. The CGI is bad... even by made for TV standards. Many of the effects are so cartoonish, I laughed. The military scenes have too many errors to catalog. Where did they find the ancient Jeeps? Brittany Murphy's makeup is often garish and distracting. I could forgive all of this if the story were mildly engaging. Sadly, it is not. I didn't care about the characters at all.
