Okay, time to stun everyone and wade in to defend Jedi....
Jabba's palace has some nice nods to the previous two films and the banter between Luke and Han when they're first reunited feels like Star Wars, but too much of it is too damn goofy. The middle of the film just drags on, and the less said about the Luke/Leia conversation, the better. But then along comes that scene with Luke and Vader, and dammit, the film starts to right itself, and by the time the three battles are going on, the film is on fucking rails. The only thing the Special Edition improved on was the grand finale -- it made it seem like a true galactic victory, and Williams' new score has the right mix of elation and melancholy.
Jedi is 1/3 okay, 1/3 bad, and 1/3 great, but at least they saved the great for last.
