As a first generation Star Wars fan who remembers the excitement in the playground when The Empire Strikes Back and Return of the Jedi were released, I can assure that, in my case at least, although I think the prequels are largely rubbish, I do not think the original trilogy is the only place where the Star Wars saga has depth. I also think The Force Awakens and especially the hugely underrated The Last Jedi are every bit as deep as the originals. Shame about The Rise of Skywalker though. :)
