That still doesn't stop you stumbling across an older film that you've never watched before, and then finding that you like it more than your "favourite".
Wait, you answer the question before having seen every single movie? How irresponsible.
I tried my best but the session timed out before I had even finished one movie.
Simple - we'll destroy every film in existence after you've asked that question. You get to be "the movie guy". That guy over there is "the book guy". The one in the corner who everybody hates? He's the one who had to use his first girlfriend's name...
