Happy! - Grant Morrison

Nick is an ex-cop, assassin, alcoholic, jerk. Into his world of non-stop swearing, comes the imaginary friend, a blue talking horse, named Happy, that seeks Nick's help in rescuing a little girl from a killer Santa. The work tried too hard to be raw and too hard to be cute and too hard to be a cop drama and too hard to be a redemption tale, and for all that too hard work it just isn't very interesting.
