I don't think they did a bad job, tbh.
The army of wide eyed kids who watched the original film in 1977 couldn't go online on forums and twitter and whatnot to pull the plot to bits within minutes of the closing credits, so it left a joyous unsullied mark on many memories that could never truly be repeated or surpassed.
I remember watching it in the Bradford Odeon, aged 11, and before the film started, the lights went out and a glitterball descended from the roof to project a 'starscape' all around the auditorium. I thought that was amazing at the time.
Moviegoers in 2019 are a lot more savvy, cynical and hard to impress. And that's just the 11 year olds, let alone those who have had 40 years of growing up get in the way of their childlike wonder since 1977!!
I think you have to go watch these things in the right frame of mind. Don't expect miracles. Just enjoy the ride.
Personally, I've loved seeing the return of Han, Chewbacca, Luke, Leia and company to the big screen these past few years.
