First off doggy's voice is just perfect. My opinion on this is kinda biased considering I pretty much only watched 90's cartoons (which i still find the best), but I've seen cartoon network's new lineup and it's just shit. They are unfunny and try way to hard to come up with crazy episodes which never work. I also feel like the decline in animation hasn't really been covered; I remember cartoons having their characters and backgrounds do more than just constantly stay in 2-D only facing left or right with no real effort in being elaborate with the set, without many clips at different angles. Hope you can bring up the animation points later.
I really like this one, as doggy really freaks out and rants in a good tone about a cartoon I despise. His voice just adds to it even more, as the pair of a raging monolouge and raspy voice complement eachother well in a comedic style. I recommend reviewing Gumball next, it's just a pile of garbage jokes and animation.
