As the title says, this is an excellent spin-off from Dr Who. It is a pity that Elizabeth Sladen's tragic death has ended this great series. Dare I suggest that if the Beeb had its thinking-cap on they might think to have Katy Manning (as the most popular DR's assistant after Sarah Jane Smith) take over as Jo Grant (or Joe Jones if you prefer). She could finish the fifth series as, "The Sarah Jane Adventures, Featuring Jo Grant." Then from series 6 onwards, it could be called, "The Joe Grant Adventures." Of course, the Beeb have always been slow on the uptake, so I guess they won't have the brains to impliment my suggestion.
