Star Wars opinions are not generational. I don’t know why this is such a common idea when people of all opinions are at pretty much every age.
I think this idea comes from the fact that prequel fans tend to be younger. But people have been saying this for two decades now, and the 12 year old prequel fans of 2001 didn’t grow up into 32 year old prequel fans of 2021, they grew up into 32 year old OT fans. The same thing is happening to the 12 year old prequel fans of 2011 and will happen to the 12 year old prequel fans of 2021.
I think it might be closer to say the prequels have gone through generational acceptance, they’ll never be the OT but it’s become more part of the package with age rather than when they were fresh and awkward, after sticking out like a sore thumb, bit by bit more has been integrated. There must be something to the generational argument, at least I imagine it has to make a difference between growing up and having the PT introduced after the fact vs knowing Star Wars as 6 movies before you’ve ever seen one.
Prequel love I see around now I think at worst is reactionary and cover for negative ST sentiment, and at best is maybe only the first real wave of acceptance for the PT, either way I think it’s too early to call even for the PT.
