"Mercury Rising"

I want to know about "Mercury Rising", the film with Bruce Willis.  I rather not get into the plot, but it looked to be an interesting movie.  Entertainment is one of my pet peeves.  It finally dawned on me. Maybe I should just deal with it.  OCD is about doubts and about anxiety.  How do I break the cycle of doubt and anxiety?  I have decided not to think on things that are negative.  I realize that a movie and the plot cannot take over my mind like that.  I have been left frustrated as a result.  I have allowed that frustration to become an "idol" sort of speak.  Why fictional works?  Why do they bother me so?  Maybe they shouldn't matter, but maybe they do and I will never know.
