For Luke to have a Son who is an emo douche like Hayden Skywalker.
Who skulks around with a sullen look on his face.
No mention of the stupid prophecy to bring balance to the force.
No Hayden Christensen, or Ewan Mcgregor Kenobi, no cgi Yoda ghost, no mace Windu, no Darth Maul, no Boba Fett as clone of Jango Fett.
No prequel easter eggs of any kind.
No politics about trade disputes that last an hour long.
No rule of two.
No Jedi forbidden to love bullshit, or forbidden to marry and have children.
No prequel jedi who are as bad as sith and too stupid to know, who also steal children from their parents and permanently separate them from their family, because of some bullshit about emotion and attachment being of the dark side.
