It’s … Return of the Jedi? It mean on here ROTJ works for me but I can’t say that out loud. To be honest I sometimes just forget there’s another Jedi title even as someone that doesn’t mind that movie. Like I forget what the 3rd one was even called at all occasionally.
Return of the Jedi when talking out loud for me as well. ROTJ when written. Thinking about it, most of my friends do also say “Return of the Jedi” in conversation too.
I don’t thing any of them call it “Return”, but a few do call it simply “Jedi”.
