First, this series has almost nothing to do with Asimov's books other than using the title. It is just about as opposite of what Asimov intended as it could possibly be. I don't think Asimov is spinning in his grave, because he stopped watching after the last episode.
As exemplified by the last episode, the plot lines continue to be implausible and disconnected, even within the context of the world that has been constructed. With often random events and actions who's only purpose seems to be to move the plot to the next implausible random construct it isn't so much a mystery as mystery meat. Unlike episode 9, which seems to have been written by a five year old, this is a bit better and may have even been written by a teenager.
The one tolerable and interesting plot line, that of Cleon, wasn't even part of the original books and has a character completely at odds with Asimov's vision for the story. I suppose that only indicates just how wrong the decision was by Apple in choosing the show runner. The man has no idea what Asimov's Foundation was about and he has enough hubris to think he can change it completely and make it better. He is wrong.
Since I am a typical SciFi nerd and will watch all the shows no matter how bad, I am honestly hoping Apple will cancel the series.
Failing that, please Apple, leave Asimov's name off the credits and change the title to something else. Then maybe it won't hurt my brain so much.
