“Perry Mason” Season 9, Volume 1 certainly begins to show signs of fatigue for the long-running series but even so, each episode, as plug-and-play as they tend to be, are still entertaining. And with only the second part to go, the series will be complete to which point I hope CBS Entertainment will choose to release the TV movies onto DVD. But I digress, as with the other season sets, this is pricey given there are no features and it is only half of a season.
