2. In Treatment
Making its debut in 2008, In Treatment that ranks second in our list of biggest HBO flops of all time, is a drama produced by HBO about a psychologist and his weekly sessions with his patients. It started off with five episodes per week during the first and second seasons, reducing the number to four episodes per week during the third and final season.
The big idea behind the series was sitting there and watching someone’s therapy session. Well, it didn’t go that well with the public and the number of viewers dropped and dropped and dropped. Critics labeled the show as “tiresome”.
