If you want the grandeur, and set it up on a grand scale, like an historical, mythology, you need people who have experience…India can be so sensitive to incorrect potrayals in this regard. Which gives you what 2-3 names- SLB, and maybe the guy who directed Kalank?
But the issue goes beyond the visualization of grandeur. Also, you need experience directing an 8 or 10 part series, and BW directors don’t know how to do it. The format, the narrative, pacing is all different and even SLB struggled in Heeramandi.
Maybe daily TV show directors potentially can do it, as they direct hours of episodes thinking about continuity, star cast, narrative, but I don’t think they get the opportunity or the funding in their names.
