Someone with the same squirrel attention who starts a lot of books a rarely finishes one. I think for a philosophy book, it is quite accessible in the sense that it builds on common knowledge and known cultural phenomenon, not that much on prior theory you must have read. Regarding the language it is not that accessible, Baudrillard (in the culture of french intellectuals of the time) has a very dense, complex language. But it is not a dry philosophy lecture, its more like hackerman punk-rock philosophy.
The book consists of a set of loosely related essays, and the first essay "the precession of simulacra" is just roughly 40 pages. If you read that, squirrel brain is happy and you got most of the books content. The rest is just explaining this concept on modern (slightly outdated now, but culturally still relevant), cultural phenomenon. Once you understand his concepts of "simulacrum" and "image" it is very readable. Later he uses his concepts of "economic and symbolic exchange" which come from his earlier book Symbolic Exchange and Death. The concept is quite easy to grasp, the book is good but you don't have to have read it. The rest of the book builds on these concepts. So the key to making this book accessible is understanding these concepts, which for me took some thinking and time to actually understand deeply.
But, and that's important, once you worked through the book, it is a phenomenal tool to understand modern culture. So is it accessible: theoretically yes, linguistically not, but its worth it.
