ANH in particularly has lots of non-Zoomer-friendly scenes, like C3PO and R2-D2 slowly walking through the desert. That was so 70s.
That’s part of why it irritates me when people say Return of the Jedi is some kind of fall from grace for having a handful of Endor scenes in the middle. There were always parts that were “slow” throughout the trilogy by cracked out modern standards. That’s just how it is.
