It's pretty incredible how much money has been raised, certainly... but there are also just as many issues I am having with this. Why the hell does Warners need to use kickstarter of all things to get this project going? Do they really expect anyone to believe for a single moment they don't have the cash to make this movie?
It goes beyond gauging audience interest. Warner realized they could get press for doing a Kickstarter, raise a budget without having to pay it back, and get nothing but profit with a VOD / home release. It's a perfect plan, if you have a fanatical nerd base, not to mention all the double dipping: People buying the digital release for $35 and then the DVD / Blu-ray when it comes out for all the extras.
I'm not saying it's a good thing, but it's a brilliant move on WB's part.
