THE DARKEST HOUR

This movie is about beings that aren't of this world coming down and devouring all power such as electricity, etc. After that's done they want to kill all of man kind. These beings can't be seen though at all they can only see you and if you touch them or anything you turn into ashes....literally. I persoanlly haven't watched it yet but neither did a lot of other individuals because the commercials barely came on television and when it did it was a quick glimpse before it switched to another commercial. Same thing in the previews of the movie theater. Ehh, it deserves a chance!
