For me ROTS represents the failure of the SW saga in general; it is painful for me because it so strongly represents what could have been with the PT and maybe the saga in general. I used to think that ROTS was the worst movie of all time, but now I am a little wiser about its value. But sorry, ROTS is synomynous with FAILURE to me.
On a second note, it also kind of reflects the GOUT, as that could have been our holy grail, but just the small fact that it was non-anamoprphic killed the franchise for all of us and represents the obstinance of Lucas, as many in hollywood still consider ROTS to be the next masterpiece and well-crafted, which it is not.
