"Great" Films

What constitutes a great film?  There are many different criteria associated with films, but it is the individuals opinion on what really makes a film memorable and "great."  To me, a great film means having a highly praised director.  It means having someone behind the lens who really knows what they're doing, has a keen eye for imagining things, and has a sense of creativity that goes beyond what a couple actors and props could ever do.  A great director has the capability of making a great film.  Take for example, George Lucas and "Star Wars."  The movies themselves are not very high-tech compared to, say, Avatar, but they began a new era of films, inspiring many other well-known directors today.  A "classic" is also another term for a great film, meaning another crucial element would be the plot of the film.  If there is no story, there's no film.  A movie has to captivate it's audience, not bore it to death.  Movies like "Forest Gump", "Casablanca" and "Titanic" moved their audiences.  Even though all 3 were filmed in different scopes and view points, they all struck a chord in the hearts of America.  A great film is one that is well directed, involves an interesting storyline, and impacts the culture and society of that era.
