Suits was one of those shows that plays on the TV in the mornings at the gym with no volume. Without the benefit of audio, you wouldn't have a single clue as to what these people do for a living. Other than a fat guy with an anger management problem, all they do is wear suits, walk around indoors, and talk. That's it. They could be CPA's, investment brokers, corporate executives, insurance underwriters... I guess they are attorneys based on Google.
NCIS, all three series. Somewhat entertaining, but complete total BS. Having grown up in a Navy environment, my recollection of the real NCIS was that they wore either suits or uniforms, didn't carry guns, and rarely ventured off base.
I actually prefer to watch the true crime documentaries. Some of the true stories are so crazy you would find them hard to believe if they were fictional.
