I thought it was my job to deprecate ROTJ.
Had the saga stayed a trilogy, deprecating RotJ is something I would understand (when I saw it again in 2004 with the dvd released I was under shock: “oh… that’s how the OT dies… with thunderous ewoks”). With the hindsight given by episodes that are no way as good (or “as less bad”), I don’t waste time against it anymore. I even now like it quite a lot. The qualities outrank the bad sides. I still think it’s better than anything released after 1983 (even if I like RotS and I find TPM and TLJ very decent… I may rank TLJ higher than TPM one day, still undecided yet…). But I totally get it can be hated as the episode that rings the bell of SW not being that awesome anymore after two masterpieces.
