Get a Roku. The Roku stick is the easiest, no cables needed. You have access to hundreds of channels including Netflix, Amazon, Hulu and all the major TV broadcasters have a channel. It's a one time buy. No monthly fee unless you subscribe to channels like Netflix. Most of the channels are free. All you need is a wireless connection for the stick.
I started binge watching Longmire and got hooked. Now I can't wait to see the new season.
