It was too little too late and badly executed. I'm not a "blame the fans" guy and tend to believe in the "wisdom of the village." If a large part of the fanbase felt their iconic hero was treated badly then the writers need to own that and apologize. I have zero problems with Luke retreating into exile like Yoda and Obi-Wan, but the character we were presented with was unrecognizable as the Luke we knew and written without intelligence or respect for him as a an established character of central importance in the franchise. He wasn't respected as an iconic hero deeply beloved by generations of fans. Instead, in the directors own words, he was intentionally subverted. Luke isn't a Jedi. He is the Jedi. He's the character that we watched grow into a Jedi on screen and who defined what it meant to be a Jedi for the entire franchise. Not in terms of code. Not in terms of technique. Not in terms of "cool force powers" That's mere trappings and window dressing and more in line with the prequel Jedi (who wouldn't exist for many years). Luke was the one who defined what it meant to be a Jedi in terms of soul. If you are going to write an arc for such an iconic and important character finding himself again you don't do it as a half-developed and poorly scripted B plot. You double-down, go all-in, and you make that the A plot. The story they hinted at in the last Jedi could have been done well, but the overall fan backlash was well deserved and to try to jam an otherwise interesting concept into a movie that wasn't about Luke was ill-advised. And that's really the point: if you aren't telling Luke's story you don't mess with Luke's story. You leave it alone and focus on your main character's story. To wit, you develop Rey and her story. For all of chapter 16's flaws (and it certainly had some) the Luke we got in the Mandalorian was the Luke many of us have been waiting to see since 1983. Unlike a lot of fans I don't necessarily want a show that's just about Luke, but when he does appear, I want a Luke who is true and consistent to the historic character many of us grew up wanting to be.

Sure, but you ignored the rest of my comment, which was that the problem lies primarily in the writing rather than the concept. He has lots of exposed fleshy bits that never seem to get hit. He's vulnerable despite the beskar. The problem isn't the beskar. Its plot armor.

One major difference: We had only ever seen them in the OT when those films came out. The PT didn't exist. They actually got a power up and positive makeover in the PT. Luke got the opposite in the ST. Word.

New Arquitens Data! Moff Gideon's light cruiser launched 2 TIE fighters and hand 1 more TIE in position to launch when Bo-Katan crashed the Lambda in the landing bay. Then, when Mando steps off the Lambda, we get a shot of 5 more ties still sitting in their racks. Arquitens TIE complement: 8.

Well, Beskar is effectively standing in for Cortosis,. In terms of risk, that's a writing problem rather than a conceptual problem (IMO). His Beskar armor isn't fully articulated interlocking plates. There are places the plates don't protect. When Mando is targeted with a massive barrage of blaster fire he should probably get grazed, if not suffer a more serious flesh wound, here and there.

Is there an equivalent of the seismic charges we see used in The Clone Army Doth Attacketh in the books?
