I read the books (the first one anyway) and it doesn't affect my enjoyment of the series significantly, IMO. I recognize that they're very different mediums and written in very different contexts, so it's fine for them both to be their own things.

An analogous case that I think is probably quite similar to this was "I, Robot." The short story collection was classic and I enjoyed much of them, and the Will Smith "adaptation" was extremely different. But The Will Smith movie's story was still an exploration of the Asimovian three laws and so IMO was worthy of being included in the "anthology." I thought it was a good movie.

Generally speaking, books make for poor movie scripts and vice versa. The best adaptations require a lot of changes. The only prominent counterexample that comes to mind is Lord of the Rings, and even that one garnered a lot of complaints about the bits that were cut or tweaked.
