Seriously, this series has really high production values, as well as superb characterization and writing. The characters are very entertaining with good dynamics with one another.
Favaro is basically a murderer for hire, despite his goofy mannerisms.
Amira is a good natured, innocent killing machine.
Kaisar is a bit harder to peg, but all round he seems like a good guy so far. Has a bit of chivalry to him at the very least, even if he's kind of one note so far.
