Honestly, the whole thing feels like a thinly veiled scam. It isn't that he's doing something "wrong" by raising funds in any way he sees fit, but it seems like its not very transparent what's actually going on here to the kind of person who would "invest" in this.
To me it's not an outright scam like the "OMG LOOK AT MY 9 YEAR OLD WHO'S BUILDING A GAME TO PROVE HER MEAN OLDER BROTHERS WRONG!!!"
This is more of a tasteless, poorly thought project that is riding the wave from Veronica Mars. At least VM offered the movie as part of their rewards. They also explained that the project had been stalled because producers didn't think people were interested. I didn't back it since I thought they didn't really need the cash either and could get it from private financiers, but if their goal was to show there was an audience for a VM movie I can accept that.
On the other hand, Braff is saying, "I don't want to work with a studio because they'll compromise my vision, so gimme." Unless I'm mistaken he didn't mention anything about studios or producers not being interested or having trouble pitching the project. So he really, truly doesn't need kickstarter at all. But he knows he can pull it off because he's taken the time to do AMAs on reddit and appear to be "cool" with the all the fans and young whippersnappers on the internet. If Braff is whining about his artistic vision being compromised or not having say on final cut, someone should call him a fuckin' whambulance. Ask Ridley Scott how he felt when Kingdom of Heaven was butchered down to its theatrical cut. Every person in Hollywood, even top directors, has to work with producers and reach a medium ground. This often involves compromising a part of their vision. Braff thinks he's an exception to this?
And that's the problem. Kickstarter is about giving a chance to people who can't otherwise get their projects off the ground. Braff is just being selfish, greedy, and lazy. But he's going to meet his goal, so I guess more power to him?
Like I said, I'm waiting for the Michael Bay Transformers kickstarter.
