Really unique tv series made in United States in 1960 year. If a tv series can manage to keep me hooked for the whole time, that's impressive. Perry Mason - Season 9 got all what a tv series should have and I am pretty sure that who watch full tv series will just enjoy it. In my opinion, some of the actors roles were just a masterpieces. A very positive for me was the role of the main character. Believe me, for a long time after the end credits, I felt confused.
