In 26 years I never heard a single complaint about the Dagobah scenes.
Look no further than Dan Vebber’s “50 Reasons Why Return of the Jedi Sucks.”

13. Obi Wan's Appearance to Luke
In case you missed the first two films, Obi-Wan Kenobi is supposed to be dead. In Wars and Empire, he made himself known to Luke through an occasional voice in the head or in a floating vision. In Jedi, all of Obi-Wan's street credibility as a wizened spiritual guide is thrown out the window when he appears on Dagobah and shuffles around like Fred G. Sanford in a coat of glow paint.
Rather than floating in one place, he fades in 20 feet away and walks up to Luke, eventually resting his non-corporeal butt on a rock. The ensuing two-way conversation scrambles to tie up too many loose ends at once, made worse by the fact that the character saying it all shouldn't even be there on such a literal level. And unlike his similarly flawed Dagobah appearance in Empire, Jedi never lets us see Obi-Wan fade back into oblivion once his message is delivered. For all we know, he and Luke could have spent hours hanging out and gossiping like housewives.
27. Yoda
In Empire, Yoda was a sagacious sprite who brought to mind Gælic legend. In Jedi, he's an annoying toad who sounds like Super Grover (thanks to Frank Oz's forgetting how to do the voice) and looks about as realistic as his Kenner action figure likeness (thanks to bad, overlit cinematography, see point #3).
Like the movie he's stuck in, Jedi's Yoda is lacking in wisdom and festering with cuteness. Get out your laserdiscs (okay, or your videotapes) and compare the two Yodas head-to-head. You'll be surprised.
39. Yoda's Death Sequence
Yoda says, "Soon will I rest. Yes, forever sleep." Less than four minutes later-Bam! He's a goner. And what does Luke do while his beloved master lays choking and gasping for his final breaths? Well, he just sort of sits there like a doofus and watches him writhe in pain. Not that dialing 911 is an option on Dagobah, but a simple "Hey, Master-you okay?" would have been a nice gesture.
41. Paradoxical Lessons in the Force
Yoda says the only way Luke can become a Jedi is to face Vader. Minutes later, he says it's unfortunate that Luke rushes to face Vader. This in addition to Yoda's assertion in Empire that if Luke faces Vader, he'll become an agent of evil. So he needs to face Vader to become a Jedi, but he can't face Vader or else he'll become a slave to the Dark Side. This is a paradox on par with the one Kirk used to confuse and blow up Nomad.
45. Generally Dumb Dialogue
[...]
Yoda, near death, to Luke: "Remember: A Jedi's strength flows from the Force." (That's more of a first-day lesson, isn't it, Yoda? Something tells us Luke had that particular bit of wisdom written on a Post-It-Note and stuck to his X-Wing cockpit long ago.)
I hope Danny Boy has gotten laid in the years since he wrote this, because it seems like he needed it.
