I think a lot of "Star Wars fans" built up the series in their heads as some kind of incredible tour de force of film making, rather than the silly, inconsistent and schlocky sci-fi that it actually is, and built their entire personalities around worshipping this idea of these movies in their heads, so when the Disney sequels came out and were safe, generic slop, it pissed a lot of people off because it wasn't like the perfect movie in their heads, but neither were the og movies anyway.
