Capital Critters was considered a extreme failure of the network. However, I did enjoy the show during it's short run. It was one of the many prime time cartoon shows being experimented with. The plot of the show is focused on the lives of the resident rodents of the White House. I believe it failed because it never found it's niche audience. It was aimed towards slightly older audiences, with plot's such as drug abuse and addiction as well as other teenager problems. However, the mice and rat characters threw people off as to the age group it focused on. The big draw when the show came out was Neil Patrick Harris performing the voice of Max, the main character. It had a unique look at teenage life, and it was really enjoyable.
Despite the fact the critics laughed at it and considered it a failure, it was a very good show. I had many friends that watched it regularly and we really enjoyed it. Prime time cartoons have had it tough until recently, and if this show had come out into today's market it might have made it, at least longer than it did then.
I enjoyed it, you might too.
