With this show's mix of animals and humans, it's starting to remind me of Chip and Dale's Rescue Rangers and I'm not sure that's a good thing. You might want to ease up on using Lex Luthor, he's a bit over the top in the deliously evil department. Almost a characature.
I did love the Dog Stars. UFO fire hydrant! Hot dog the weiner dog! Let's see more ot them.
