Triple 9 is essentially The Town and any David Ayer cop movie on steroids. It did have the potential to be a really good cop/heist action-thriller, but it suffers from a weak screenplay. It is a couple of re-writes away from being a strong cinematic contender along the ranks of Casey Affleck's brother Ben's heist thriller.
As mentioned, Triple 9 suffers from a weak screenplay in that all the scenes and sub-plots work well own their own, but never find the right footing when it comes to working well as a whole. The entire movie feels as though it were a 6-part miniseries that was chopped down to a 2-hour movie. Is there an extended director's cut out there that can help with this.
Even with this weakness, the actors did a great job at bringing these characters to life. Each and every one of them were believable as troubled dirty cops. The action sequences were well-staged, but as I mentioned, they all work well on their own and not as a whole.
I mentioned on Social Media, as I was watching this, that the movie did a great job at making Atlanta feel like a hot and grimey city. That alone helped in letting me viewing feel the world these characters find themselves in.
Triple 9, however, managed to keep me on board for the duration of the movie. I cared enough about these characters to see where the story went. Its a forgettable cop movie, but one that you should watch anyway because I think you may enjoy it even more than I did.
