I started watching this this week and I am really enjoying it. If you like The Preacher you'll probably like this. It's based on a 4 issue comic by Grant Morrison, and funnily enough is drawn by the same guy that did The Preacher comic. Nick Sax is an alcoholic ex-cop turned hitman who lives his days with drugs and cynicism. After he is shot and left for dead, he revives while in the care of paramedics and can now see a small, blue, goofy cartoonish winged horse named Happy. Happy is the imaginary friend of a little girl named Hailey, who has been kidnapped by a deranged man dressed as Santa Claus. Happy escapes to seek Nick's help in finding her and reveals that Hailey is Nick's estranged daughter. Nick reluctantly agrees and he and his new "partner" now must work together to save her.
