Religious 101: What is a Pope?

Due to the recent death of the Pope, i thought i'd get more of a clarification as to what the Pope actually represents to people of faith:

"...The Pope is the Catholic bishop and patriarch of Rome, and head of Roman Catholic Church and the Eastern Catholic Churches. In addition to this spiritual role, the Pope is also head of the independent, sovereign State of the Vatican City, a city-state entirely surrounded by the city of Rome..."

"...In Catholicism, the Pope is supposed to be Christ's representative on earth. He is the alleged, visible successor of Peter..."

"...word originates from the word father, ie: 'papa'..."

Did anyone watch 'End of Days' with Arnold Schwarzenegger? I thought that for a religious-themed movie it was pretty cool to watch. It shows us in a mild sense how the Devil really is the 'great deciever' and how he/she can bring the worst out of us. The Pope (an actor, not the actual Pope) was also in the movie, and he sounded like a very wise and just religious leader, which is why i mention the movie.

Im really sick of these 'Crazed and prejudiced fanatic' religious leaders like the taliban and that Brian Tamaki guy (Destiny Church). Im sure their are some out there that are good and pure. Jesus and Muhammad be proud of us...

Are their any other good religious-themed movies out there? NOT Passion Of The Christ - I watched that with a catholic friend and it was horrible; She almost cried and honestly i can't blame her. Maybe constantine??
