Any move away from Freud is going to be a positive move, an evasion and ironically a reduction of human scope. So from the negativity of the Weltschmerz "period", see book below, we see a positive way of evasion through the Super Man (Nietzsche), and I don't know D&G, but if you will read Russell Jacoby's book, Social Amnesia, you will see various moves by other psychiatrists and intellectuals (essentially happiness coaches) to evade Freud's pessimistic evaluation of man's lot.
For a long time it was a veritable industry to outdo Freud, to do better than him, and I don't think anyone was able to improve on him, though there are many who dislike his message (if they ever got his message to begin with).
To get reality into the Ego space, which could be the space of reason, is so, so difficult, since from "above" it tends to be "contaminated" by Super Ego, and from below subject to the
upswelling urges of sex and aggression.
When I mention the "Weltschmerz" book by Beiser, I do not mean to say that Freud is the same as Schopenhauer, etc. Freud was his own person, he had his own theories and so on, so I mention the Weltschmerz book only to give historical context.
Social Amnesia: A Critique of Contemporary Psychology, Russell Jacoby (Beacon Press, 1975; Transaction, 1997) Available Internet Archive. This book comes at the end of Freud studies, not at the beginning. Neo-Freudian in this book is not a good thing, but is seen as a corruption of Freud.
