The massive media attendance at Comic Con indicates that producing Sci Fi (and I do use the term loosely) is almost the sole occupation of the entire movie, TV, game, and publishing industry. Try going to your local multiplex and not have to choose science fiction as some thematic component. Of the top 10 box office hits of 2013, nine are sci fi (only the Fast and the Furious 6 is not)...
Implied in the Kickstarter funding concept is that somehow the hard core genre fanbase would do a better job of bringing (or reanimating) some much beloved work or franchise. This ignores the role of producers, hard working key grips and this thing called professional actors. It also ignores this thing called accountability. Believe it or not, if something is good, it's good for just about everybody. Being terrified of being cancelled can bring out the best in a work.
Many recent well-deserved box office bombs are the result of betting on the hard core allegiance to marginal sci fi classics. "Ender's Game", "John Carter" etc...without realizing that it's more important to just make a good movie.
I use the term sci fi loosely. Of the REAL uncut stuff all you need are the pulp magazines, cover by Michael Whelan and this undeveloped resource called your imagination. Crowdfunding could really help with the marginal economics of magazine publishing. Who the heck wants to WATCH a bunch of space academics debate how to run a foundation.
