Plus, these channels have opened up more categories of film to wider audiences. Big budget, full length films and multi-season tv series aren't the only viable options anymore—some of the most talked about media in my circles over the last couple of years have been limited series. Try dragging a brilliant 8 hour limited series across an entire 23 episode season or trimmed down to a two hour film and it's a completely different story.
Brilliant film makers are still brilliant film makers and the number of studios willing to take a chance and fund them has never been greater. The traditional movie-watching experience is still here, it's just no longer the only option. I don't think declaring the movie business as dead is accurate, it has simply evolved and adapted. But from where I sit, this evolution has just given us more stories and more ways to hear them.
Just because you can distribute a story without a year-long PR blitz doesn't mean you can't tell a good story.
