1. It Places Quality and Consistency at Risk
While it can be argued (correctly) that quality was often at a premium in the prequel trilogy, Star Wars fans were more inclined to forgive those lapses simply because George Lucas was personally responsible for them. For all the hatred and invective they so enjoy spewing in Throatzillas direction (He raped my childhood! being a personal favorite of this writer), Star Wars geeks love Lucas unconditionally for being the guy who created Star Wars, whether they admit it or not. Disney is not going to enjoy the same long leash from the fan community, and it would behoove them to realize it sooner than later (e.g. before they release a Star Wars movie that winds up a critical and/or commercial failure). Announcing an ambitious and open-ended release slate of one movie per year was not the prudent course for Disney to take. If things start going south even a little bit in the first film or two, theyre going to be screwed in a big way and left with no exit strategy. The smart and judicious thing, artistically speaking at least, would be to focus all their energy and resources on making Episode VII the best it can be, space the sequel trilogy episodes three years apart so they have room to make adjustments on the fly should the need arise, and make the production of any standalone films contingent on how well-received the first two episodes (at least) of the sequel trilogy wind up being.
