I finished "The Signal" on Netflix. It is a 4 episode limited series. I think it is German. It's awful. When I watch a sci-fi series I want the main characters be be intelligent. Dumb characters make it hard to sell a sci-fi story. In this series one of the main characters acts like a complete idiot. It is not intentional I don't think. I think the writers think he is actually fairly smart. He just seems oblivious to everything obvious. I will say the story itself is not that bad, but this series kind of ruins it with the usual clichés about earthlings being so horrible to each other and the planet, blah, blah, blah. How do we know how aliens behave with each other or with their own planet? Maybe they are worse than we are! In any case, I would not waste my time on this show. It is another Netflix series they bought from a foreign entertainment company to fill their lineup card - kind of like the way Jerry signs cheap players to fill his roster.
I also finished "Ripley". This is an 8 part series remake of the movie with Matt Damon, "The Incredible Mr. Ripley". Different actors of course. Why did they make the movie into a series? I have no idea, but in order to get 8 episodes they dragged out some scenes from the movies to the point where you scream at the TV, "Just get on with it!". It becomes apparent at the end that Netflix is going to have a season 2 with an entirely new storyline - assuming season 1 gets any attention. I am not a Dakota Fanning fan. Maybe she was cute as a child actress but all grown up she looks like the biological daughter of Bette Davis and Mr. Potato Head. If you really liked the movie I am not sure how you will react to this series. IMO, the main character, Tom Ripley, is not likeable enough to pull of this plot. If there is a season 2, I probably won't watch it. I give season 1 5 out of 10.
