Well, I'll still argue that ROTJ is the least of the OT, but it's the Jabba stuff I mind while the ewoks don't bother me at all. Aside from Luke's part of the story and Leia's kick-ass bikini, everything seems to be either a retread or not as well-realized as the previous movies. And it certainly didn't benefit from suddenly becoming the last chapter of a trilogy when it was originally supposed to launch three more sequels. Obviously the main problem was the Leia/sister thing that always felt tacked on and implausible, even when I was nine. And Robot Chicken brilliantly parodied the end of the movie with their scene of the imperials arguing why they can no longer fight back even with Vader and the emperor dead. But while I agree that the Jabba stuff was fun adventure and showed off Luke as more heroic, I stand by my reasons I posted when I started this thread. It seems it was written to let the characters do things, but nobody seemed to bother to make sure it actually made any sense or was an intelligent plan.
...which it wasn't.
