Actually it seems, that this project was cancelled, not because of a lack of experience, or a lack of resources, rather, the rather rabid vitriol that is typically spewed out towards anything even remotely connected with JJ Trek (As it seems this film would have been set within the Context of the Nu Timeline.)
It goes both ways. There are fans who treat fan films like shit, railing and insulting and being entirely rude and vicious with their comments.
Likewise, there are those fan filmmakers who are their own worst public relations enemies, unable to handle ANY kind of commentary or critique, and whose nasty, biting demeanor is less than pleasant to behold.
Personally speaking, given how sensitive the entire community is and can be, I don't blame the guy one iota for getting out while he can. Trekkies are crazy!
