As a Bulgarian, I could hope that this notorious
heterogeneousness of Bulgarian cinema is the main reason for the amazing
disinterest and ignorance to the subject in the English language critical
literature and scholarship (though it is really hard to be so naive to
really believe it). Ronald Holloway seems to be the only Bulgarian film
scholar writing in English, who at least knows the subject at first hand,
while the very few other critical attempts are either occasional film
reviews or second hand "accounts, drawn from the limited recent scholarship
and reviews, of this neglected film culture." Bruce R. S. Litte complains
that "Bulgarian films are not available to film students, to say nothing of
average viewers; nor have they become available on video", but he does not
specify whether this is the cause or the effect of this almost total
disinterest to a whole national cinema.
