Everything about this series was perfect, from the acting, to the scripts, to the directing, and even to the fact that black and white was used even after the advent of color. Of course, Raymond Burr WAS Perry Mason, just about the world's greatest defense attorney, who stops at NOTHING in his search for the truth. The supporting cast was also excellent, and the guest stars, unlike in so many other series, were always of a high calibre. Some might say that the scripts were a bit formulaic, but within the basic format, over the 10 year run of the series there was infinite variety in the details of each show, with enough unexpected plot twists to constantly keep any audience guessing. The atmosphere was perfect: black and white lent a mysterious, almost gothic feeling to the episodes, which at the same time was beautifully contrasted with Perry Mason's ice cold reasoning and razor sharp sense of right and wrong. There are so many other things I could say about this series; perhaps it is best left at saying that this is the one, the only court drama, probably the best TV drama in general, and definitely one of the ten greatest series of all time.
