Movie studios are in the business of making money. They are going to make movies that audiences will see. You and I can bond over not wanting to see OBSESSED, but it doesn't really matter, because more people paid to see it this weekend than anything else.
If you want to get into this business with the intentions of making art, of conveying your vision, of being experimental and avant garde, go ahead. There are plenty of people making independent films and otherwise artsy things. But if you intend to make a living in the mainstream Hollywood system, you have to learn to accept that money and audiences matter.
I don't see why you can't try to do both. Make a good film (or TV show) that people want to see. I think this is the goal of most people, really. Even money-focused studio executives never sit down and think, "let's make a piece of shit." They think, "let's make something millions of people want to see." I think it was Scott Rudin who said something like, "With the privilege of making movies comes the responsibility of making them great." And something tells me he's not suffering through bowls of Ramen for his art.
DL, I think your question actually has a lot to do with attitude. If you think that all the movies and TV shows out there right now suck, you're probably going to have a career of frustration and disappointment. You're not gonna show up and change how it all works.
I think it's important to be informed and to think about the big picture - sometimes. Mostly, though, I think you need to worry about writing a great script. Write stories you're passionate about. Don't waste so much energy being a hater.
