From the perspective of Lyle and Eric, their mother withdrawals emotionally and turns a blind eye to the sexual abuse they experience at the hands of their father. She doesn’t leave but she definitely checks out and says she doesn’t love them. So I think it’ll still potentially be upsetting for folks who are triggered by parental abandonment.
Child abuse is a major part of the story/case so it is discussed frequently and is pretty much unavoidable if you’re watching the series. You will see teenage boys being verbally and physically abused by their parents. You will hear graphic accounts of them being abused as children.
One of the brothers sexually abused the other when they were both children. The abused brother forgives him because they were both abused by their father, and he was reenacting what had happened to him.
As a child, the older brother was abused by their father and then reenacts the abuse he experienced on his little brother. Discussed, not shown. Also it’s implied that the abusive father was himself abused as a child. So, big yes.
At the end of 38 mins - well into 39 - Jose describes a horrible collar for dogs/talks about a dog they once had in a very upsetting way. Skip or mute because it's no visual images, just dialogue.
Birds are shot at in episode 4 (nothing seen on screen, and it's very brief). A story about a dog killing a ferret and then being killed is in episode 7 (skip 5:02-5:17 to miss it completely).
Graphic descriptions of child sexual assault throughout, but particularly Episide 5, the entire episode is one of the brothers describing in detail how their parents abused them sexually, physically, and emotionally.
If mentions of or seeing someone commit suicide is a trigger, skip episode one. There are several depictions of Erik having suicidal thoughts and it graphically shows the nightmares he’s been having. If seeing this would trigger you definitely don’t watch episode one. You could start on episode 2 and probably still be able to understand what’s going on.
The show explores multiple possibilities and perspectives (the kid’s version of events, versus the parent’s, versus the outsider’s) and sometimes these conflict with each other.
F word used several times. The timeframe for a lot of the events is also at the peak of late 80s and early 90s homophobia following the AIDS epidemic, so there’s a lot of casually homophobia rhetoric throughout.
Two brothers dance together in an uncomfortably sexual manner. Happens near the end of the Vanilla Ice sequence. There are hints of incest before this but this is the first overt display. It will likely ramp up from here, based on the rumors and records of the real events surrounding the case.
