These shows are very big productions, and it takes a ton of time, both on the production side and in post, so you have to respect the long journey for some of these shows to deliver what hasn't been done on television before," the Netflix executive continued, explaining why production on "Avatar" (and others) has been taking so long. "And that's what we have for a lot of these types of shows when we're working on them, whether it's 'Avatar' or 'One Piece' or 'Three-Body Problem,' these are big, visual spectacles that you have to honor the process and respect that, when you're breaking ground in visual storytelling, or you're on the visual vanguard of storytelling, that takes R&D, that takes a lot of trial and error to get it right.
