I never found it to be full on teenage angst to be honest
Apart from some anachronistic jokes and stuff, the writing as a whole isn't teenage angst, just the companions are. It's as if the rest of the game was written by someone at least half-competent, but the companions were subcontracted to some shitty dating sim writer. There's no way that someone who fought numerous battles in hell would speak like a horny college girl. Wyll is possibly the most "classic" of all the companions, but somehow people find him boring. I personally like his story of a tainted would-be hero.
Funny thing is that if you choose not to romance any companion, Withers even scolds you for it.
A sidenote: there's a huge ludonarrative dissonance when it comes to the companions' looks and their stats. Halsin's STR is 10? Doesn't matter, let's give him body that would put a bodybuilder to shame!
