WARNING SPOILERS
To me it's a great show. Not only for the technical part (I had nothing to say about it 'till the bluetooth hacking just before the escaping of Vera from the prison, but the flow of the story needed it so I think I can get over it) but for the accurate study of the character's personality. We can see almost all kinds of personality we can find in today's society and I really like how they portrayed the main character. It really hit me, the authors managed somehow to create a link between him and the audience (probably thanks to the fact that the main character sees us as his imaginary friend).
Plus I have to admit that the cemetery scene really struck me, I couldn't believe it.
An interesting Easter Egg is the one where Tyrell enters the arcade and Elliot explains him what he did and why, pay attention to his words and the song playing in the background (tribute to Fight Club?).
