If you believe I am off base, I welcome suggestions of thinkers who are an anti-pattern here.
FWIW, the most concise and straightforward critical theorist that I've read is Vilem Flusser: https://en.wikipedia.org/wiki/Vil%C3%A9m_Flusser
There's a short compilation of his essays called "Writings" that is a great place to start, for anyone interested. Most essays are < 15 pages long, IIRC.
Very simple, elegant arguments, with little fluff. One of the few philosophers I know whose writing is absent the usual obscurantist cruft.
I don't think critical theory is particularly insightful, or internally consistent except by which it's proponents fit it. It makes many predictions, but most are true only through the lens of critical theory. Looking in from outside, there's other explanations of all the predictions.
Much like Marx: it's an interesting, intriguing theory. But it breaks down at some point, except that people already attached (and it's easy to see why it's an attractive view of the world, simplifying things into a constant struggle against the "oppressor"; the classic narrative) will do great contortions to explain why it's still true, rather than going back to the drawing board.
Of course, you can level the same criticism of libretarian ideals, and they do break down. I think libretarians have a more consistent view of why the break down and where, but it's imperfect and I greatly await a more grand, unified theory.
If you haven't read him, I'd recommend the "Labyrinths" collection as a great place to start.
Hofstadter's book is brilliant, funny, delightful - a real treasure.
He's not a major philosopher like Kant, but he is much more than a charlatan or provocateur.
To his credit, I probably wouldn't have picked up his serious work if his antics hadn't first put him on my radar many years ago.

Partially Examined Life podcast did an episode recently on the book. The ideas are related, not quite the same.
Contra another commenter, I don't think it's easy to separate Marxist critique of capitalism from spectacle / simulation replacing reality - I do believe that capitalism is responsible for the alienation, the alienation doesn't just apply to the labourer and his output, but also to consumers and what is consumed.
Very much this, though I must also recommend his Comments on it, for the reader who has a hard time penetrating the critique. I have a short list of related books at the bottom of this comment: https://news.ycombinator.com/item?id=15299592
