Guys when referring to movies like Pirates I know they are good movies, but the cost for the actors, special effects, and advertising can run in the 500 million dollar range. I guess Pirates is a bad example since it was tremendously popular, but think of movies like "Day After tomorrow" or "Superman Returns". Most people enjoy them yet these movies are so overbudget that they barely turn a profit. "Day After tomorrow" cost about $140 million to make and ticket sales amounted to $186 million.
Meanwhile 'crap' movies like Big Fat Greek Wedding make ~$450 million in cinema sales alone and cost the companies less than a million dollars to make.
Like I said, people and studios like the big budget movies, but they finance them with all the other crap that they put out there. Same deal with PS3/360 games and the Wii
