I watched this TV show with my aunt, a woman who REALLY loves "Dr. Who". After we watched a bit, she said "I really don't want to watch any more"...and that probably explains why many Whovians had little to no interest in this show and it soon disappeared from TV.
The biggest problem with this show is that unlike "Dr. Who" which could appeal to all ages, "K9" clearly is something only kids about 12-15 might like...MIGHT. Having annoying kids in the lead sure alienated us and the show was very talking and annoying. The only thing good I could see in all these shows are some decent aliens...the costumes were very nice quality. Apart from that...it actually grates on you as you watch it.
