With all respects to Lucy Maher, the CommonSense reviewer for this show, I'm a little surprised that she didn't realize that this show is a pure mocumentary and not supposed to be real. It's all fake and a spoof like "This is Spinal Tap" or "Best in Show". Perhaps she hasn't seen either one of those before?
I think the show is hilarious, just like "Spinal Tap" was (for those of us old enough to remember), especially in the way it spoofs hip-hop and people trying to get famous. I think this show is fun for teens and even pre-teens, although younger kids probably won't really "get it." It's fun for parents watching it with their older kids too.
In the episodes I've seen, aside from some bleeped out language, I really didn't see any really objectionable issues.
