Movies based on September 11

Recently, I have heard a lot of discussion regarding the Movies based on the tragedies of September 11. Until this week, I was only aware of the movie United 93. This is the story the passengers and crew, their families on the ground, and the flight controllers who watched in dawning horror as the United airlines flight 93 became the fourth hijacked plane. The movie recreates the doomed trip in actal time, from takeoff to hijacking to the realization by those onboard that their plane was part of the coordinated attack unfolding on the ground beneath them. The film attempts to understand the fear and courage of the passengers and crew onboard as they became bonded allies who confronted an unthinkable solution. The story also includes actual conversation that passengers shared with their families.
When I went to see the davinci code this week, I saw the preview for another movie. This one is called World Trade Center and will come to theaters in August. This is about the true story of John McLaughlin and William J. Jimenez, the last two survivors found under the rubble of Ground Zero and the rescuers who never gave up on them. It stars Nicolas Cage who plays one of these two NY port authority police officers.
Part of me wants to see these movies, if only to learn more about what happened on that tragic day. However, another part of me does not want to see them at all. I don't want to relive the tragedy, it was hard enough watching it all the first time. Another reason I don't want to see World Trade Center is because it is mostly based on the firefighters and police officers who risked their lives in an attempt to rescue others. My dad is a firefighter and honestly, movies such as this terrify me. My dad is great at what he does, but sometimes I fear that he is just a little too selfless. I fear that he would be the one to volunteer to search for others, even if the odds weighed against him. Just watching the prevew was hard for me because I can't even begin to imagine what the families of thee people must still be going through.
I really can't believe that this September it will aready have been five years. It seems like it just happened, I remember the events so vividly. I don't think I will see these movies just yet, but perhaps someday I will. Because I do want to know as much as possible about what happed that day.
