From the same minds that brought you Brickleberry and Paradise PD. That alone should tell you exactly you can expect from this series.
Personally I'm a fan of both shows and their raucous sense of humor is right up my alley. The voice cast consists of the same people who worked on those two previous shows and as viewers familiar with them will tell you, the characters shown here are deliberate rip-offs of the ones that came before such as Prince Fichael who is drawn just like his counterpart Steve (Brickleberry) and Kevin (Paradise PD). Same goes for most of the main cast with the only new addition being the awesome Lance Reddick as Fichael's egotistical father the Czar of Planet Fazar, Renzo. Although Reddick (Bosch, John Wick, Resident Evil series) is no stranger to the animated shenanigans brought to life by creators Roger Black and Waco O'Guin. Previously he voiced FBI Agent Clappers, a man with a particularly large set of rhymes with spectacles in Paradise PD.
So here's the thing, humor is objective and what works for some won't fly with others. I for one find the dirty jokes, fast-paced zingers and over the top plot points in Fazar to be a laugh riot. Lance Reddick's distinctive voice (anY Destiny 2 fans out there?) is one that drips with sophistication and gravitas, so to hear him dropping f-bombs left and right while discussing the downsides of having sex with a much older woman or throwing insults at his idiot son Fichael cracks me all the way up! It's like the first time I heard Morgan Freeman swear on screen (I think it was in the movie Wanted) it's both shocking and laugh out loud funny. I also love everything that comeS out of the mouth of the shows apparent antagonist. An alien named Bazarak who spends more time planning his attacks on the city of Fazar, than actually following through. It's all mindless, odd and deliberately stupid and depending on your sense of humor, it will either keep you in stiches or bore you to death.
