Some people like naked female breasts.
I'm all for breasts, but when the tits are more there for titillation rather than serving the story, then it's just a turn off to both titillation and story (GoT is the worst at this, of the HBO shows I've seen). And there's more HBO elements there too. The typical "tell not show" aspect where they have some lame, contrived excuse to have monologue-ing. Sopranos did this with the psych sessions, Deadwood had the bj monologues. I forget what else had that. The typical cliches are there as well but because HBO is doing them, it's suddenly compelling drama! They seem to get a free pass on lots of things. HBO is extremely overrated, to me.
Anyways, as for the show if you're still watching, I really hope that Rust doesn't turn out to be the killer just cause of his past undercover work with shady people, him hanging out with that prostitute and doing drugs, his familiarity with occult symbols, his detachment from women, the way he has all these intimate insights into the psychology of the murderer, and him having nearly all the breakthroughs in the case instead of the other guy. It'd be a bit too ham-fisted if it turns out to be him. I'm guessing they were under pressure from government and hardass boss to make a collar so they pinned it on some fall guy earlier.
