Very well made series. Each episode is focused on a different gang, inclusing interviews from current members, former members, aswell as the law enforcement agencys attached to investigating that gang. Definately some parts that may be hard to watch for some people, it is an understatement to say that this contains violence. My only 2 issues with this show is that it was made for people that watch 1 episode at a time, if you plan to sit down and watch a few in a row, you will find it gets repetative. Aswell, the first season is the best one by far, contains all the major gangs, the show kind of goes downhill from there, but thats not to say it gets worse, just not as good as the first season. I grew up in a very gang dominated city and throught i knew a fair ammount about gangs, apparently i was wrong. This series is a definate eye-opener.
