Why Is It?

Ramblings on the way things are....
 Why is it that in movies, they make who they are portraying alot attractive then they actually were?
Like with Nowhere Boy about John Lennon and forming the Beatles.
Here is Aaron Johnson who played John Lennon:

Not to be rude, because I love John Lennon because of his music and who he portrayed himself as, but clearly Aaron is way better looking. Do they think we won't watch the movie unless they are ugly? Even though it is historical? I believe that we focus to much on the looks and not so much on the personality. If you aren't pretty, or if you aren't skinny then you aren't accepted. But everyone can lose or gain weight, and that is easy when compared to trying to change yourself, because real change comes from within.

Everybody loves you when you're six foot in the ground.
-John Lennon.

To me, John Lennon is a great inspiration, he fought for peace and love while not turning into the constant jerk that most famous people turn out to be. I love everything about John Lennon including his music. If I could go back in time, and tell him how much I appreciated his music, I would. Without a doubt that is my one wish in life.
Rest In Peace John Lennon, and may you forever be loved.
