Most filmmakers spend years fine-tuning their craft, yet still wary of making a terrible film. Short film after short film, struggling to find the funding to make their dreams come true. It's all apart of the American film industry.
But some filmmakers find their fortunes sooner and are able to do what they please. The Room is one of those films, where either the director had too much money, terrible actors, and even worse, a poor crew; or was genius at his craft, so much that making a terrible film was his form of expression.
I doubt the latter.
