Most of the channels I may have been interested in watching have slowly descended into drivel: Discovery, History, TLC, Science...they all show total garbage reality shows 24/7 these days. A huge portion of the hundreds of other channels we got seemed to be essentially filler garbage to inflate the channel count.
Aside from the content, the UI/UX of the whole cable experience is terrible. Our cable box was brand new and 'top of the line', yet was so slow that I'd sometimes count the seconds between selecting something and seeing any sort of feedback. The 'cloud DVR' service–touted by our cable provider as a premium feature that would allow you to watch recorded shows in other rooms or on different devices–would regularly simply not function, or, especially on nights when a popular series was premiering (Breaking Bad comes to mind), would throw 503 errors when trying to watch the recording.
We were spending upwards of $150/month for service, and they kept trying to sneak in rate increases. Towards the end of our lease neither of us-even my TV industry roommate-watched anything on TV. Cable TV is a terrible service and I'm glad to see that it's getting shaken up.
