Like any show, I never watched the X-Files until it went't off air. One day while watching television I saw an episode not realizing it was the X-Files. I was incredibly surprised. From my point of view, all the seasons leading up to the 1st film (film is in my top 50 science fiction films) were superb. After the film, with the exception of some episodes, things just got too ludicrous for my taste.
The X-Files is a great franchise that has been hit with a lot of blows. I think what it needs is really good film that is dark with an incredible story. What director? This is the type of film that is perfect for Christopher Nolan.
Then the series needs someone like J.J. Abrams to reignite the series. X-Files fans are fanatical and with a good film and series, the audience could grow exponentially.
