I can't believe that the fans are trying to explain why force lightning reflected of Windu's saber and not Obi-Wan's, all because Lucas failed to compose a reasonable story of why Palpatine looks like a monster in ROTJ.

Lucas was too keen to reproduce craft, scenes and characters as they were 16 years later in the timeline of the OT, as I and others have said, its a shame we didn't see earlier versions of Vader & 3PO (like McQuarries designs) or Palps disguise slip when he attacked Windu & gang, only to be nice again when declaring himself Emperor in front of the senate.

Its a miracle that the Falcon didn't make more of a cameo!!
