Even the criticisms that Disney's sequel trilogy is a "slap in the face" to the established lore is bizarre coming from people that almost universally love the EU content.
"hur hur somehow palpatine returned, what trash" hey guess what there's an entire storyline called The Dark Empire that was considered canon where Palpatine was reborn into a clone body.
"Luke would never abandon the Jedi!" oh I assure you he did, in Dark Empire he becomes Palpatine's apprentice.
