I went into this skeptical but open-minded.  Sarah Jane Adventures were clearly intended for a younger audience but is still pretty damn good and fun even as an adult.  The K9 series is that kind of lowest common denominator of kids TV.  It's made on the cheap, doesn't have a ton going on story-wise, and just kind of goes through the basic beats of a story without much creativity.  It reminds me a lot of the shows I used to watch in Canada on our public broadcasting network - fine content for children, but nobody else.  I don't think even kids would find this show that funny, especially these days.  This is easily the worst Doctor Who spin-off.

It is alarmingly hilarious how bad K9 looks when compared to his original appearance.  There is some potential with these characters but all the K9 elements of the show feel like a cheesy gimmick.  I worry what the rest of the show could possibly be like because rather than improve, I feel like the low effort sense I got out of Regeneration would have only gotten worse over time.  This at least had a bit of fun in the silliness of the K9 reveal.  What more could a show possibly offer so thoroughly divorced from the rest of the franchise?  K9 is not the kind of character that could ever carry a series on his own.  People barely seem to like him as a companion, even though I think he can be fun in the right context.  This is the opposite of the right context, though.
