If you're a fan of South Park, Archer, Rick and Morty, or other irreverent adult cartoons, then you might like Animals.
Keep in mind that Animals is a dialogue-driven cartoon, and the animation kind of takes a backseat. The writing and improv drive this show to hilarious places. The animal characters are all voiced by funny actors, some of whom you'll quickly recognize. Some voices I remember are Aziz Anzari, Adam Scott, Chelsea Peretti, and Jason Manzoukas (the dude who plays Rafi in The League - such a funny actor). The real stars, however, are relative unknowns. Mike Luciano and Phil Materese are the main writers, directors, and voice actors. They have great chemistry playing different versions of Mike and Phil thru all the Animals episodes. It sort of reminds me of the great dynamic that Dan Harmon and Justin Roiland have in Rick and Morty.
I saw Animals advertised on HBOgo and decided to give it a try. The first two episodes (Rats, Pigeons) can drag here and there, but they're still really funny in their own right. The payoff comes at Episodes 3 (Cats) and 4 (Dogs). Those episodes are some of the funniest television I've seen in years. I don't want to spoil anything. I'll just say this show will make you see your dogs and cats in a different light. In a good way though. You might empathize with your dogs or cats a little more in a strange, acid-trippy, "I can now speak with animals" sorta way.
It's a bummer seeing the relatively low IMDb ratings of this show (as of 2/27/16). I only watched the first 4 episodes and am eagerly waiting to watch the rest once they're released. I never write reviews of shows, but this one compelled me to say something. Imaginative and well-written, well-directed shows like this aren't easy to find.
Animals is more of a slow burn. There is an over-arching story involving human characters intertwined in all the animals' episodes. In this world, the human characters don't speak. The animals don't shut up. The humans are despicable. The animals are complicated. It's fun.
I recommend this show if you enjoy some cheeky banter between animals. You'll never see a dogpark in the same way again.
