It's probably a good idea. If you can get distribution, this whole discussion becomes moot, right? Does it mean it's a waste of time discussing this any further?
Well no one ever made 6 figures getting their film in theatres across the countryon their own one by one
Depends on your definition of success and your goals. I've read a number of case studies in where the filmmaker was happy with the results. Most of those were 6 or 7 figures. So I guess that's a success, right?
If you really want to know, google for case studies on self distribution. I'm sure you'll find something. Not sure how relevant it'll be to your film. You'll have to make that determination.
Larger distributors have more leverage to ensure a better chance of payment. It's part of the reason to get reputable distribution. There are of course downsides. Some of them are significant.
