I personally have found nothing at all useful on any channel on my Roku TV. Anything useful at all seems to be pay per view. Which I don’t want to do.
I have 3 roku and get some good use from them. There are hundreds of free channels depending on what you like. NewsMax is conservative news and free. Skynews gives you current news with the lib slant. Then you have History channel PBS Pandora and Youtube. With Youtube you can see either entire episodes or the highlights of many current things. I use Amazon Prime to get a ton of movie and TV content that is not realtime but who cares.
There are tens of thousands of programs uploaded to YouTube. Use the search function on the YouTube channel to find programs that interest you.
