Dead wait - A headless chicken is shown freshly decapitated and flapping on someone's bed .. Appears real, I'd think it is, coz it was probably cheaper to get a real chicken than invest in a battery operated prop.. Skip from 17.20 next 10 seconds... Head of a dead ram shown briefly pinned to a wall
Someone uses a tarantula in a way to get to someone else - and the other person smashes it. :( if you like them it might upset you, it not - it will but bug you
Strip club scene, if you consider nudity sexual content there's tons of breasts shown. Also a scene where a nude woman (back) and man are in a hot tub.
Season 1 episode 1, the main character is extremely mysogynystic about women, and says some pretty repulsive things - using the word whore to refer to us, and multiple other things. It was uncomfortable for me to sit through - and I usually dont care if I'm watching something. If this kind of thing bothers you, skip it.
