welcome to our struggle. Maybe you should join it.
To me, the simple answer to your question is that what we're tying to do is really fucking difficult. You would know that, if you had ever tried it.
Ha ha! A lot of truth to this comment.
I doubt any one of us set out to make a dud. The problem for indie filmmakers is that many armchair critics compare 50 million dollar movies to our self funded, made in our spare time efforts and wonder "what's wrong" with them. Well, with money, you can hire experienced people in many positions. There are large crews on those fancy looking productions and they do the work that can't be matched by one, two or three indie guys in multiple roles.
The only solution for lack of money (aside from being born with amazing talent) is to persevere and leverage a tremendous amount of experience, either from "doing it a lot" or somehow surrounding yourself with people who know the craft. Again, the latter is hard to do, as those people need to be available for the duration of the shoot. That's when time becomes your enemy, so you might have to shoot a feature in 5 days, like Vince Rocca did. Or, you can do it without the crew and take more time.
I read one of Sonnyboo's blogs that said Robert Rodriquez made 200 shorts before the "accidental" success of EL MARIACHI. That was no accident. Yet, I'm sure a lot of people think that EL MARIACHI looks like crap, but the more you take the budget into account, the better it looks!
Along those lines of Big versus Small, I would say that all the big budget gloss is killing the allure of things we loved as children, that might not succeed as well today - Kirk fighting the lizard man, Lou Ferrigno running around as the Hulk, Steve Austin running in slow motion, etc. I've alway like the low budget charm kind of like movies like LASER BLAST, BASKET CASE, etc. Those kind of productions gave me motivation to eventually try filmmaking for myself. I thought I could do better, right out of the gate, but there's more to it than that.
