Some great TV shows have made their way onto DVD this week including: Mighty Morphin Power Rangers: Season 1, Vol.1 - most of the action is just as fun as you remember it to be, and you'll fall victim to the theme songs hook for some time to come; Leverage: Season Four - A step up in quality from season three, this fourth season is fun, energetic, and immensely entertaining; and Mannix: The Seventh Season - Another solid season from this veteran detective series. Other shows recently reviewed include:  Bonanza: The Official Third Season, Doctor Who: Death to the Daleks, and The Kent Chronicles.  Want more?  Check out all of the TV on DVD reviews in the DVDTalk database.
