Harry Potter, Lord of the Rings, Narnia, The Da Vinci Code... It seems that most big franchises today are adaptations of popular books (and comics). While it has resulted in some very good movies sometimes I can't help wish that Hollywood could come up with some ideas of their own. They could once. Even as late as in the 80's there were a lot of very successful movies that weren't adaptations, like Back to the Future, Ghostbusters, Beverly Hills Cop, the Indiana Jones-movies to name a few.
