Oh, IP-driven films bomb for sure. I'm not saying they're infallible. I'm saying studios would rather make those when there's at least a chance they'll make their money back.
By the way, I, as a member of the audience, am not saying I don't want more original, director-driven films. Of course I do! I'm just speaking from the studios' point of view. Scorsese is complaining about "Where do directors go to get their movie financed?" and I'm saying unfortunately gone are the days where the GA showed up to those movies with enough regularity for them to greenlight all of them unless they can take it to the bank with certain directors (Nolan, Tarantino, probably Inarritu now etc.).
I'm basically putting some of the blame on the audience. Hell, you can also put some of the blame on cinemas and ticket prices. There are a lot of factors that go into the film landscape nowadays. Studios don't make these decisions just cuz. They follow the market, and WE set the market.
