I was 23 when I saw ROTJ it in the theater, and I loved it. I still do, and I don't agree with a lot of the criticisms of ROTJ. But that's probably because I never expected it to be as good as SW, which I first saw at age 17 and thought (and still think) was one of the most brilliant films of all time. Films like that are, to quote Han, one in a million. On a scale of 1-10, I've always ranked the films something like:

SW-11
ESB-8
ROTJ-7
TPM-5
AOTC-3
ROTS-2

The truth is, I never liked the Vader-as-father and Leia-as-sister angle. It just made the universe smaller and hokier. Once they went that route, there was pretty much no way to grow a real saga. To me, SW is still SW, not ANH. But Yoda was cool and Jabba was cool (well, not in the SW-SE, but in ROTJ). And of all the SE revisions, those in ROTJ are surely the most ghastly.
