Let's make this clear so we're all on the same page. Training Day was a damn fine movie. Led by a bombastic performance from Denzel Washington, the 2001 movie from Antoine Fuqua put law enforcement, power and insanity under a microscope and fried them like ants.
What made the film so great was a sense of grittiness and rawness in such a tight package that could only get its message across in a film with a definitive ending. Washington's Alonzo Harris got his in the end, as it should be. The story was told over a couple hours and lessons were learned. You see where I'm going with this?
CBS' adaptation of Training Day for the small screen loosely borrows from the Training Day formula -- old crazy cop shows young idealistic cop the ropes on how to really get things done on thug-plagued streets -- but turns it into a serialized cop drama fit for network television. It's hard to say whether we're supposed to applaud that decision or not. On one hand, we'd criticize the show if it rehashed exactly what the movie did. On the other hand, going in a different direction takes away everything that made the movie so effective.
It's a no-win situation for CBS, so the network chose the option that made the most sense for itself: turn Training Day into a sustainable TV series that doesn't stray too far off brand from CBS' other police procedurals. That meant tinkering with a few things, most notably taking the vet cop -- played by Washington in the film and Bill Paxton in the series -- and humanizing him as often as possible so that audiences will relate to him for seven seasons. You can't have a star of a show be someone you don't like, right? The problem there is that takes away exactly what made the film so great.
Riding along with Roarke is Kyle Craig (Justin Cornwell), a rookie cop who has such a good day out on the job that an LAPD deputy chief tells him he's now going undercover to keep Roarke from going Alonzo. Craig is fairly run of the mill here, an idealistic cop who tries to do the right thing and struggles with Roarke's extreme methods.
In order to turn Training Day into a TV show, Craig and Roarke are tethered together by a common goal. Craig's dead father, who also happened to be Roarke's partner, was killed under mysterious circumstances, and these two want to find out who did it. So while they have fundamental differences in the way things are done and nearly get each other killed constantly, they do have this off-the-books murder investigation to keep each other around. And that's how you make a TV show out of Training Day.
