This review is actually a critique of only one aspect of this episode, and that is the writing that reflects exceptionally poor police procedure--procedure that I can't believe would actually ever happen in the real world. So at one point early in the episode (this isn't really a spoiler), Olivia convinces her brother Simon, who is wanted by the feds, to meet her at a bookstore cafe. A federal agent goes with her and plans to take Simon into custody.
Naturally, as *always* happens in these poorly-written scenes, Simon begins to "smell a rat" and he bolts, running out of the bookstore to escape the trap Olivia has set for him. Some trap! The federal agent is nowhere in sight, and Simon escapes.
Now in the real world, that federal agent would've positioned himself near the front door, or at some other obvious site, making it more difficult for the target to just walk out of the place unimpeded. This is one of my "pet peeves" with these shows--"Hollywood writing" intrudes far too often. Just for the sake of drama, like an extended chase scene, the police do completely unrealistic things they would never do in real life. For me, this ruins the episode.
Memo to Hollywood writers--Have people do and say real things that real people would do in real-life situations. No one yells at a suspect when they're 50 yards away from him and only on one side of him. They wait until they have him surrounded, until they have his escape routes blocked off. That's just common sense. These police shows are the worst offenders for this kind of thing.
I suggest that if the writers, directors, and producers would exhibit more common sense in their scripts and productions, their audiences would show their appreciation by viewing more often.
