Yeah, I kind of got a kick out of it, but not for the reasons the film-makers intended. This is one of the few disaster movies that makes "Armaggeddon" look like it was written by geniuses and "The Core" like it was made as an instructional film for use in college geology courses. The wide liberties taken with actual fact (and common sense) make for a rollicking time, but it scares me that we're failing in educating the youth of today.
I mean, this is only 3 hours long, but in that time you learn that the screenwriters (1) think that the moon has a magnetic field emanating from a core, (2) believe that the "laws of gravity" are that "little objects are attracted to big objects," (3) don't know that cruise missiles are air-breathers and won't operate or even steer in the absence of an atmosphere, (4) don't understand the difference between electromagnetics and gravity, (5) think that it takes longer to walk back to town from a car breakdown than to program, launch, and deliver 87 rockets with nuclear device payloads all the way to the moon, (6) have some bizarre ideas about what a brown dwarf star is, and so forth.
But it IS entertaining. Just make sure to have a chat with your kids afterwards to make sure that (a) your son didn't spend the entire movie following Natsha Henstridge's boobs, and (b) that your daughter understands that the science end of it was all BS so she won't be afraid to get her graduate degree in physics. After all, any exposure to the "scientists" in this film is an almost guaranteed turn-off for budding researchers.
