There was this feeling during the buildup to the prequels that Star Wars was alive again after a long slumber. People dressing up in costumes, acting silly, sharing nerd camaraderie, camping out in crazy long lines, bringing their kids, and so on. Even the Special Editions didn’t shake it – we simply didn’t know at the time that the Special Editions were intended to supplant the movies we loved, we thought they were just an experiment gone wrong – a soon-to-be-forgotten footnote. This deluded, hopeful “it’ll get better, it has to!” feeling stayed with me, at least a little, until the second prequel. Oh, but as for something good that was actually IN a prequel… I got nothing, sorry. But that hopeful feeling was still pretty good.
Basically, the original trilogy was so potent that the fumes from the OT kept the fans happy for decades, even while the franchise was actively being destroyed. But that fume-y period was a happy, albeit naive, period.
I don’t think TFA captured that feeling at all. People were looking for something to rescue the franchise, they were really hoping it wouldn’t suck, etc. Relative to the prequels, people were pretty sober about it. Even now that TFA’s proven to be much better than the prequels, the fumes have cleared. We’re not naive anymore, which is a shame in a way.
