You mean their judgement to keep going back to fans for more and more cash?
It's better to raise the funds you actually need up front (despite whatever waves of monotonous "oh noes they're fundraising again and I am Very Suspicious About This" nonsense this might attract) than to land yourself in the predicament Renegades found itself in, it seems to me.
Axanar has already raised 3xs what Renegades raised, and is looking to raise another 3xs what renegades raised....
Concern about how Axanar went from being an 800k movie to being an almost 2 million dollar movie, is legitimate, and now, other than, "its gonna be great" (now we know where Trump got his campaign strategy) they haven't really explained it.
This production has a history of over promising and under delivering (the perks being a primary example). And BEFORE anyone mentions the difficulty of perks for the number of donors they have, they STILL HAVE NOT updated their donors page with the names of people who donated to their last Kickstarter... A year ago....
So yes these concerns are legitimate...
