Not really. I'd say that although unorthodox Marxists the situationalists would see themselves as following on from Marx. After all, the whole of The Society of The Spectacle begins with a reformation of the opening to Marx's Capital!

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
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.
