Do Androids Dream of Electric Sheep?

I don't know how I feel about this book. I don't know if I would rate it 3.5 or 4.

In my opinion, the main premise of the book is between reality and virtual/unreality.

The main point being the thin line between android and humans. What makes human “real” and androids not. If Mercenism is in the end, reality or a lie.

The question goes even further than that, throughout the book, as a reader, you find yourself reading through events where you keep wondering if what is happening is real or not (e.g: Dickard's meeting with Phil Resch)

However, I find the execution lacking in many ways. The book is trying to tell too much and doesn't take the time to do so. As a result, events are rushed and major elements are left underdeveloped.

Some characters make no sense to me, for instance, I don't understand Isiodore's character. He is clearly the personification of empathy but he has no adding value to the story.

And the ending is, in my opinion, a mess.
