Actually, the section header was framed as a question.  You appear to have answered it.  Now, to address your answer, you've actually seen the "vast majority of fanfilms"?  I call that into question.  Besides, your statement smacks strongly of the implication that "the sample is the whole".  Even if I were to concede that many fanfilms are bad for the purposes of discussion, your statement strongly implies that you no longer need to check out individual fanfilms to pass judgement on one.  I'm sure that you're aware that "most fanfilms are bad, this is a fanfilm so it must be bad too" is an over-generalization fallacy, and again I'm surprised that an educated debator as yourself would use that even as an implication.
