To even begin enjoying this show, you need to have an enjoyment and interest in all things to do with the American law and order system. So if you don't enjoy Law and Order than it is highly unlikely you will enjoy this.
I however do and so enjoy this show every week. I like the lead characters of Brogan and Peale and especially enjoy their interactions together. At the moment I will admit a lot of the supporting cast are much more stereotyped than they should be but that is usual of any show that is just starting out.
The one part of the show I most enjoy is that as the viewer we aren't told whether or not the person committed the crime or not. We are allowed to wonder throughout the whole episode. It actually makes you feel kind of like a juror.
I can't comment on how realistic it is in relation to the reality of criminal law but what I can say is that it is an enjoyable hour of escapism with a lot of room to grow and improve.
