Virtually nothing happened.
What I mean by that is NOT that the episode did not have its octane moments (Clark/Peters annihilating the break-in kid) or that it wasn't intriguing at moments. However, and this is a big however, it was reminiscent a lot more of Sopranos or Mad Men in that we simply followed the day-to-days of protagonists rather than what the Wire did - present their lives but wrapped up in a combustible, interesting relationships, situations and settings. Inevitably, that leads to let-downs.
In the episode, things 'simply happened'. The question that we must ask, though is - would it matter if they didn't - and the answer, for the most part, is a resounding NO. I can appreciate the getting-to-know the now ex-DJ Sonny (Zahn). I can even go with the 'son in jail' story because the payoff was - the system doesn't work even when it apparently does. But the length of the tourists/street performers time throughout the episode was just unnecessary. All these small snippets of the hardship of lives is too much, not because they shouldn't be shown, but because the intensity is on the level with our lives - and that makes a good documentary, not a good (durable) drama.
Personally, I don't care much for the music in the show; but I don't mind the emphasis. However, if a major emphasis of a show doesn't suit me - I'm just not going to watch the show.
Oh, and *where are the bad guys*??? I know that sounds immature, but if everyone's an anti-hero and if the only true bad guy is the system, we're going nowhere - plodding.
So, in short, a let-down from the last week and in general. Hope it bounces back.
