Oh come on. Looking at what is going to do better in the marketplace before deciding to make a new product is only good business sense. There's absolutely nothing wrong with it unless you decide to make a genre film that you know nothing about.
And to be honest, I don't buy the whole "I'd rather go broke..." bit. The starving artist routine I don't buy. There's a lot of things I could do to go broke including sitting on my butt doing nothing that I would prefer doing than the enormous task of writing/directing/producing/representing a movie, IF there was only the prospect of going broke.
I don't care whether everyone here wants to make films with other people's money that make very little or no money. I say do it. But for everyone who wants to make something that might have a chance at securing a good distribution deal, and more importantly, might be seen by a sizable audience, it is necessary to study what works and what doesn't. Bend the rules, break them, whatever, but to pretend there is not a fairly well-defined hierarchy of what sells and what doesn't is just plain ignorant. I see that everyday, but I also see indies who CLEARLY understand what works and what doesn't, and they have shaped their style and storytelling to a very polished technique... oddly enough about that time name talent want to work with them, producers want to finance them, and they start making money.
And, in line with "making money", I think its pretty clear if we wanted to make a million dollars, we'd all be better off getting an Master's degree and getting a 9-5. Many of us are not cut out for that, but are willing to take a chance on doing what they really love and enjoy for a living, if it has the potential to provide at least enough for us to survive while we do it. But to blindly start spending money after money and shrugging it off when it doesn't pan out because: A) It has no marketability B) It is not incredibly innovative or original and C) It does not have the polish most high end films have, is simply, IMO, a bit mad. Not that mad artists haven't found success in the past, they just usually end up drunken penniless messes by the end of their lives.
