It is a series of strong events that we live in differently with former security guard Jake Hewitt, who is following a 24-hour training session with a rogue informant. It looks like a very interesting story, as it seems that this man is not what appeared on his first day working as a drug officer in Los Angeles, which may be very strange.
Viewers could do worse than tuning in every week to see Frank troll department heads about a lack of donuts in staff meetings, but Training Day doesn't show enough in three episodes to merit its origins.
The series is committed to flirting with a walk on the dark side, but because it's essentially a CBS procedural, it can't or won't go all in, and instead remains on the margins of its characters' moral ambiguity.
