I did the same thing years and years ago. He liked the prequels more than the original films, and now its the opposite since he has grown up. He also is extremely opinionated and thinks the Last Jedi was the worst movie ever made because of what they did to Luke. Quite a turn to be honest since he liked Hayden Anakin and now Luke is his favorite and the unaltered OT.

My niece on the other hand really likes the Disney trilogy. And Rey. Really likes Mando and Baby Yoda, and Clone Wars and Ahsoka. She doesn’t really care about Luke, Han or Leia or any other Boomer characters. I explained its Gen X not boomer.
