The show is really improving. I know it's mainly focused on Missy Peregrym but it's good to see other characters doing something for a change.
Although Diaz and Dov are supposed to be used as comic relief they are great characters. They show some reality and make us feel sympathetic towards their rookie status.
I personally enjoy seeing the senior officers in action. They bully the rookies for a little bit but they also help them understand the procedures and how to deal with the new situations they are facing.
I know Peck's character was made for the sole purpose of being the annoying character with a sensitive but hidden side but I just hope we see more of her good side.
