I wanted to like the show as its not set up like the generic Police shows, (it is an anti hero bad police show) and I could of liked it if they hadn't over done the shaky camera shots, to be honest at time it was more like watching a TV show in the middle of an earthquake. I believe as an earlier reviewer said they were trying imitate 'The Shield' going for gritty realism .The difference is in The Shield it was a real effect they had cameramen taking shots with hand held cameras. In The Oath they have used a tripod then created the effect in post production and they have over done it.
There is also a problem with the amount of edits, they are constantly cutting from shot to shot. I get that they are trying to keep it fast paced but having so many edits takes away from the acting, it is a failure to show or give the actor the chance to act.
So overall it had potential but it has been spoiled in post production
