We must be hanging around different social groups because I was actually fairly impressed by that. For a few years now it's become popular to bash RotJ whilst regarding ANH and ESB as the literal breath of God. It would have been very easy (and safe) for him to fall in line with this sentiment, but instead he goes and picks the least popular OT movie as his favorite, and is actually able to back it up with specific scenes he enjoyed.
The true normie opinion would have been to proclaim ESB as his favorite.
Star Wars sperging ahead:
Nearly all my friends who grew up on the OT love RotJ. It's easily the most highly revered of the three in my peer group.
I used to think ESB was the best of them, mainly because the tone was so different especially when compared to the shiny, almost candy coated look of RotJ. It's kind of like the conversation between Dante and Randall in Clerks when Randall asks which one Dante liked better: Empire or Jedi. Dante likes Empire better because he's a doomer and says the events of Empire are more relatable because life is "a series of down notes". Randall thinks preferring Empire is "blasphemy".
Jedi was my favorite when I was a kid. I loved Empire when I was an edgy blackpilled teenager/twenty-something who didn't care about shit. At my advanced age, I absolutely think A New Hope (or "Star Wars") is the best. It's a simple, self contained story with an ending. It's a timeless, good vs evil story that appeals to people of all ages. There's no real moral ambiguity (aside from Han being a scoundrel) and everything is neatly wrapped up. If they'd left it at that, it would be considered a one and done classic like The Wizard of Oz instead of a tired ass "franchise" that turned off half its fanbase.
In many ways I think ESB was the beginning of the problems with Star Wars, specifically Vader being revealed as Anakin Skywalker. That one thing hamstrung the whole narrative when you take a step back and look at the entire saga. All the problems with that single plot point are laid bare in the prequels and show just how little of the story was planned out in advance.
As for Jedi, I think it's the weakest and most poorly written of the trilogy. Not to say there aren't good things about it. The space battle at the end is glorious. The final confrontation between Luke, Vader, and the Emperor is a fantastic moment and the lightsaber duel between Luke and Vader is brutal and contains more emotional intensity than any of the flashy, flippy, over-choreographed dance numbers that came after. Jedi has arguably the best score out of any of the films in the entire series.
But the writing is unforgivably bad and lazy. The second Death Star is an absolutely awful, uninspired idea and should never have been the finale. C-3PO had no business joining the Endor landing party and was only useful to speak to the natives that nobody knew even existed because they all thought the forest moon was uninhabited. Han Solo and Chewbacca are never in the Falcon one single time in the whole movie and
that's what they do, for fuck's sake. Lando is cool and all but him and Vagina Face zipping around in the most recognizable vehicle in the series lacks a certain something. Honestly, Han doesn't really do shit the entire film except trade shitty zingers with 3PO. Well, that's not true. He also accidentally slapstick kills the greatest bounty hunter in the galaxy while blinded, Fett's death leading to a Wilhelm scream and the second burp gag in the movie. The Leia reveal is absolute bullshit and even Lucas admits he only put it in there because he felt Jedi needed a "wow" moment like Empire had, so he just recycled it with a different character.
And I didn't even go into the Ewok thing like most Jedi haters.
