The weird thing about the show is it didn't even feel like Bethesda writing. Fallout 3, and 4 to a lesser extent, have a certain pg13 tone that, while having some quirk still has what try to be moments with gravitas. Vault 101 and Amata, Fawkes and his vault. Hell even the institute for all its retardation is for the most part played straight without much humor. Bethesda fallout, if lacking in depth, at least didn't resort to pure raunchiness.
I watched 5 minutes of the show and the sheer amount of junior high sex humor I saw in that time was bizarre. Fallout can have sex but it's not a shitty seth rogan stoner comedy from 2006. Bethesda fallout writing was poor, but it hardly ever felt tasteless. Rushed, cheap, cliche sure, but rarely crass.
The show's tone was almost like someone was making a spiteful parody.
