ROTJ had some good moments and I actually enjoy it, but Han and Leia were not the best parts.
Well we can easily say that Han and Liea were pretty much one of the main focus of ESB (if not the main). Whether there is nothing for them in ROTJ is opinion dependant. But anyway, the point is that they certainly became secondary in terms of focus in ROTJ. Partially because Lucas depleted their (romance) potential in ESB and mainly because this film put focus on Luke, Vader and Emperor. That doesn't in any way undermine the film.
Still if you compare Han/Liea roles between ESB and ROTJ from storyline perspective, in ESB they basically had nothing to do. They were just running from the imperial navy for majority of the film, and in the end they served as a bait for Luke. Not a very prominent role (story-wise) I would say. While in ROTJ they at least had some decent role, story-wise of course.
