The Glass House could have been a good show if the format was better. To me the format is what killed the show. Is you dont remember the format here is a small recap of it. The contestants are split into two groups and compete in various physical and mental competitions. The captains of the two teams are the two contestants who have received the least amount of votes from the public. After losing a challenge, the captain of the losing team is sent to limbo, along with a second member of that team which is voted on by the house. And the people who watch Glass House vote who to stay in the house.
This format made the show so predicable. Most of the time the Team Captain would be voted off.
To me a much better format would have been that winning team captain would pick 2 people to go into limbo from the losing team.
