Nah, I think it's still plenty worthy of respect as a trilogy. The first Star Wars essentially created the modern blockbuster. And similarly, the Star Wars trilogy really set the model for a big action-adventure trilogy that tells one big story/mythology. That really hadn't even been done before. Even if you aren't the biggest fan of the films, or think ROTJ sucks- you still have to acknowledge the trilogy charted a path that many franchises have followed. It set the template. Hence, worthy of respect. Not to mention the sheer impact on pop culture.
Sure, they're far from perfect as films- I love to pick at 'em myself, because there's plenty of silly things and it's fun. But as a film lover, I will vigorously defend their iconic status. John Williams' scores alone put them on another tier compared to most blockbusters being made today.
I have always argued that with TDKT, it forms a whole greater than the sum of its parts and I also think that's true for Star Wars. That's the same reason some people who find TDKR to be the weakest film, still can acknowledge that TDKT as a whole was a great achievement.
I actually agree that TDKR is a stronger movie than both ROTJ and TLJ (and I like TLJ), but I'm drawing the line at saying the original Star Wars trilogy isn't worthy of respect. I'm not going to be one of those annoying people who says "you MUST love Star Wars!" cause I get that it doesn't resonate with everybody the same and I know what it's like thinking a pop culture phenomenon is overrated (*cough* Stranger Things)...but looking at it as a film fan, they are clearly an indispensable part of cinema history, flaws and all. Hence worthy of respect, whether you like the films or not or think they're overrated.
We won't speak of the "Nooooo", because that's a 2011 Lucas edition. That ruined one of my favorite movie moments of all time.
