Dedicated Filmmakers Alert: No idiots allowed!
The major problem is weeding out the idiots before it's too late. You meet them at various meetups/gathering and they come across as serious and dedicated and then suddenly, when it's time to work, they get a terminal case of bullshit-itis.
The cause and cure is simple: 1). They don't stay in their sandbox. 2). They should stay in their sandbox.
The second point is very important because if they do that then we'll have a fair a balanced industry. You'll have serious filmmakers doing their thing and the idiots doing their thing. It works out for everybody.
Idiots, do us all a big favor and stick to your fucking sandbox! Thank you!
