I've just finished watching 'Happy!' on Netflix... really fucking good
https://www.imdb.com/title/tt2452242/?ref_=nv_sr_1
The IMDB blurb of 'An injured hitman befriends his kidnapped daughter's imaginary friend - a perky blue flying unicorn' doesn't really do it justice but the 8.4 rating is spot on, it's ultraviolent, drug fueled, disturbing and very funny.
