The result is an interesting blend of outlandish scientific absurdity with elements of the modern thriller. Science-fiction from the 1950's and earlier came from an age where modern science was at much earlier stages of deciphering the mysteries of outer space and the human body, so the science-fiction stories of the time was usually built around more fantasical plots that didn't need scientific explanations. In another recent remake of a 1950's sci-film, War of the Worlds,
"Invasion," however, is a little more science-heavy. In "War of the Worlds," Tom Cruise spends the film outrunning the alien invasion, but since he knows practically nothing about where they came from or where else they're located, one is tempted to ask "Where exactly is he running to?" In "Invasion," issues like these are well-thought: she's running to a lab that will cure her. Of course, with this outdated plot, you have all sorts of stretches like Nicole Kidman's misguided belief that by drinking lots of mountain dew and taking pills she can stay awake forever, but Nicole Kidman, Daniel Craig (who plays her boyfriend and colleague) and Jeffery Craig (playing her colleague) are such consummate professionals and they take the material so seriously, that the plot holes seem that much smaller. The film's attention to detail can be enjoyed in the same way a Tom Clancy or a Michael Crichton novel can.
