I can't believe how underapreciated "The Shield" is. Not just here, but in general. Anyway Soupysales is right, I personally don't like the Forrest Whitaker epeisodes as much as the other ones, but he is doing a great job. Note to all buy the DVD's and get caught up, or star watching on Spike TV this show is the best thing on television at the moment.
It is not for children, but it presents realistic characters in a morally ambigous world. While this may not be a completely original idea, it is done far better then any show has done it in the past. Having lived in areas of LA which have been fictionalized into Farmington, all I can say is wow.
