What Really Makes an Experimental Film?

Fred Camper made a list of certain criteria that would define a film as 'experimental.' Many people who are asked seem to describe that experimental films are not your average films, as they do not necessarily carry a narrative throughout.  That is true, but there is a lot more to it.  These certain kinds of film tend to toy with the creative minds that produced, as they challenge themselves to introduce something that has not been done before.  Essentially, to experiment with what can be done in the film medium.  These film do not necessarily need to be cohesive, unless that is what the filmmaker is trying to do.  To define an experimental film can be and is difficult, as the term 'experimental' generally is broad in the film industry.  Whether it is low or high budget, scratched or meshed together, clear or obscured, the experimental genre is nothing less than the mainstream film, maybe even more difficult to master.
