Yeah Andrew, I've read your review beforehand, but I'm curious exactly why you didn't like this movie.
The review is not to the point, but hopefully some of what failed comes through. It is frequently boring, especially some sections that seem added to just pad out the running time. Their special effects for the alien-imbued vacuum involve wires or somebody simply pushing it with their hand out of view (or, not always out of view), but scenes of the vacuum on a rampage are still few and far between. The interaction between the female lead and her annoying boyfriend are painful, as are those between the male lead and his wife. The sound and picture quality are also bad enough to be distracting at times.
