I tend to disagree with everyone saying this show is bad, there seems to be a lack of knowledge from the rookies but thats part of the appeal. I think the writers were really trying to humanize the characters and show that cops don't just pop up being all bad ass and knowing all the stuff they know. This is really more of a training camp for cops from the very start, clearly they know the very basic but the instincts it takes to solid interrogation or street smarts while on the job are just not there so I'm gonna chalk that up to realism of the first few weeks of being on the job.
The second part that comes to mind is the cast, OK there's a massive fluctuation in dynamics here they need to really break down a few characters instead of just doing a scatter shot and hoping you like 1 main and 1 of the 50 other people they toss at you, I mean diversity is one thing but having so many people clumped up into 1 show is just a complete loss on the focus of the show, it makes everything seem incomplete because of constantly breaking away from one pair and moving on to the next.
Final review 7/10 too much stuff going on at once, simplify a bit and you'll have a solid show.
