I don’t quite see your point.
Lack of self belief, lack of able professionals and as of now, a relatively small market. They’re so overwhelmed by bollywood that they lack the initiative and confidence needed to make something original and creative that will cater to their own audiences. Also you need an insane drive to build something from scratch given the lack of film making infrastructure in Pakistan. The censors aren’t helping anyone either, though t hey have no qualms passing bollywood through.
A few people DID try to do something different than Lahore industry stuff during the 2000-2005 period-- Rauf Khalid, the guy who’s dad directed “Armaan”, Fahim Burney etc. – but all of these were sucky films which evidenced BAD film making skills rather than lack of audience interest. Since desi film makers are superstitious and tend to believe in the herd, no one has since launched something promising, though really these films which failed were pathetic films and deserved to bomb.
