The idea that fan films cannot be creative could only come from somebody with a very limited view of fan films. I invite you to come to Star Trek Reviewed and watch the following:
Steam Trek: http://startrekreviewed.blogspot.com/2009/06/7.html
Stone Trek: http://startrekreviewed.blogspot.com/2009/06/8.html
Star Trek Aurora: http://startrekreviewed.blogspot.com/2009/06/8.html
Turkish Star Trek: http://startrekreviewed.blogspot.com/2009/06/28.html
Stalled Trek: http://startrekreviewed.blogspot.com/2009/06/50.html
I have limited myself to what I call "Golden Age" films... but there are many more unique and creative efforts.
