I have similar views to the above. At school, ROTJ was commonly known as “Muppets in Space” due to some of the silliness in Jabba’s palace and the ewoks. The Leia/Luke twist felt contrived, and I hated Boba Fett’s demise by total fluke.
On the plus side, I thought the speeder bike scenes and final space battle were truly epic, and loved the visuals and atmosphere in the throne room.
