The only thing this series has in common with the classic science fiction books by Asimov is the series name and the names of the main two characters, and maybe a couple of plot points. Almost all of the details have been changed or added, and not in a way that is consistent with the ideas of the original. And I am not talking about details like making Gaal female, that type of change is ok.
I guess that I could just consider it a different story and enjoy it on its own merits if it had many. The first few episodes were just not that good. With the exception of Jared Harris (ok, at least that was great casting), I found the acting sub-par, the plot seems disjointed, the pace very slow. So far it is just a vehicle for some enjoyable special effects
