This is not entirely fair. TPM and AotC are genuine dissapointly movies. I would personally qualify TPM as an outright bad film, and AOTC as a soldily below average one when looking at them on their own merits. ROTS, on the other hand, takes a lot of flak that it does not entirely deserve for being associated with the other two films. It is certainly an above average science-fiction fantasy film and certainly capable of standing next to most of the 'good' blockbuster films of the past decade-plus. Episodes I and II traded very heavily on the Star Wars name and would have been much, much less successful without them, especially in the domestic box (the worldwide box office has a much greater tolerance for action-oriented science fiction than the US does, see exhibit A: Battleship). Still, the tyranny of expectations does matter. The OT is a set of modern masterpieces, living up to that is all but impossible. TPM would have suffered some backlash even if it had been a genuinely good film, but it would have been considerably less. We can see this in other reboot/adaptation scenarios. The better your product ultimately stands on its own, the less wailing their is from the fans. The Harry Potter series is actually a good example, the films are generally considered to have improved through their run, and carping about adaptation difficulties quieted down. How expectations will influence the ST is not yet clear, however. While the younger audience, less interested in storytelling and more interested in lightsaber battles and simply more tolerant of the PT in general, is probably burning with anticipation, much of the rest of the fanbase, and the wider public, are far less enthusiastic. The very biggest fans: the Star Wars fanatics who live and breath the whole universe, are largely side-tracked by the larger issue of the EU's uncertain status and will remain very hesitant until that issue is resolved. Many others are jaded by the PT, and other Lucas failures, notably Indian Jones IV, and simiarly worried, though there is a group that is elated Lucas himself has stepped aside. Ultimately, producing a good blockbuster is surprisingly difficult. There's a particular set of skills relevant to working with the epic canvas that many directors and writers simply never develop, especially in a modern scene which has turned away from the format (prestige-wise). There's a reason Michael Bay has become modern blockbuster royalty despite possessing basically one top tier movie-making skill (the art of making things blow up in truly awe-inspiring fashion). The ST is heading into uncharted Star Wars territory. I give maybe a coin flip chance of being good. The chance of it being truly great, almost none.
