This movie is more historical, they did a great job trying to join past footage with new ones.
The important part of the movie is to show how hard it all started and how religion played a key role in uniting everyone something that does the same this days and the opposite depending on your way of thinking.
Another important part is how the more you spend time together and give each other a chance they will get to know each other better and understand each other.
Treating each other with love spreads more love.
Lastly sports is the best way to get together! It is very true!
