Have seen up to episode 13 on the K9 solo series. It is still not particularly good. They keep having K9 laugh, which is kinda bizarre to hear. Also they seem to be developing a love triangle between the three kids. They look about 12! WTF?
The best episode so far has been episode 10, Curse of Anubis. The Anubians are hilarious - Egyptian-themed aliens who worship K9 and look like half-naked blokes with Sutekh heads on. There's a bunch of references to Old School Who monsters, and the main cast get dressed up in hilarious ways.
