Obviously he doesn't have the budget to do a hundred takes...but I think that speaks well of de Leon in comparison with Kubrick. That hundred take thing, I think it's more self indulgence than anything. To do it well and right on at least the first few takes requires discipline and balls.
That said, de Leon is a perfectionist. You can see it in his films, where everything is technically and visually perfect. His films are even technically better than Brocka's, Bernal's, O'Hara's. It helps that he has his own lab.
