He's got a point though, and I think of film as both ways. You need to tell a story the way you feel it needs to be told, but it's a waste if nobody "get's it." So while a lot of people agree there's wiggle room in how you can tell a story, there still needs to be people who understand it. Like the Air India flick you watched, the guy next to you understood that form of story telling. It wasn't just random shit pulled out of some guy's ass, it followed their story structure. Essentially Bollywood does the same thing Hollywood does. Films are made to entertain, in the truest sense, at the very least in the film maker's own mind. If it didn't, people wouldn't watch it, because by definition watching is entertaining. At the very least you need to follow your own rules, Kubrick for example didn't use a three arch structure. But he still kept a constant method. I don't think a film maker can just willy nilly do what they want if they want to make a good film. They have to follow their own internal rules at the very least. As David Croneberg once said, there's nothing you can't do in film so long as it fits within the film.
