I don't really think it's an age thing either. I grew up with the OT as a teen. When the prequels came out I was in my 30s and really enjoyed them, maybe except for TPM in the beginning. But even that grew on me a little later. I was older but basically the same person, intellectually, emotionally, more or less same taste etc., during the sequels era. And I certainly didn't like TFA, not on first viewing, and not even slightly more now. It's safe to say I'll probably never be a ST fan. My nephew, at that time (TFA release) around 13 or 14, likes both the OT and PT, but as far as I know not so much the ST. So it's clear that there are other factors involved, not just age or time.
