After the 3nd episode they just ran out of the content such a exiting concept, and mystery came down to solving an murder that is not even important, I mean who cares what happened to him or who killed him we're exited in finding the truth about silo and going outside. when the power went out after 140 years and the screen suddenly turns into lush green earth for 1 sec, such a good turn on scene but was ignored like nothing every happened and people have zero doubt or questions about outside. Just make small or less episodes but don't ruin a good series by stretching it and making it a turn off. There was so much more that could have been added but they just got tired after putting all of their energy in 3 episodes.
