I do agree it is not as good as the wonderful Rocko's Modern Life, but CatDog is not that bad. Actually it is decent. Yes some stories are predictable and some of the jokes are somewhat tiresome, but there are some intriguing and sweet story lines such as Lube falling in love and there are some good jokes and solid writing.
The animation is quite unique, and I liked this unique style. True it is not the best looking of the Nick shows, but the animated style is colourful at least. The music is also pretty good, outstanding no, good yes. The characters are funny and engaging, especially Lube, who is moronic yet likable, and the voice acting as far as I am concerned is superb.
Overall, this show for me was actually pretty decent. 7/10 Bethany Cox
