Alien obduction...invasion...conspiracy....government cover-up....no, it´s not x-files
Although there are some similarities Dark Skies takes a fictional plot and puts it inside actual historical events. It works in a this-is-how-it-could-have-been way. There are a bunch of historical figures involved in the story. The plot was supposed to cover four decades, from the 60s to the new millenium, unfortunately it fell short and I think got cancelled in the end. Which was really a shame as this was one of the most promising plots I had seen. So this will go into the history books of TV as another "what if...." show.
Come to think of it, I guess Spielberg took the general plot idea for "Taken"
