To be honest, I couldn't watch the whole episode, because I got so bored by it.
The reason it gets(well, reasons) 4 instead of even less, is Anthony Anderson, who does a BRILLIANT job, just like in The Shield, and the other one is the portrayal of New Orleans. It's scary how realistic it is.
But any other way, this episode failed. The writers are not exploiting the options of Katria at all. Just another crime show with zero originality.
I don't understand this. If you have such a good set, why not make use of it?
Of course, it might improve. Because there is so much potential in it.
