Highly recommended.
Start with this list:
Pluto
Netflix
Amazon
Crackle
Tubi
One America News Network (4.99 per month, but worth it times 3)
Depending on where you live, your local networks will offer a Roku channel for live news. This is big for local weather and traffic.
Popcornflix
There are others offering classic movies for free too.
YouTube is available over Roku, awesome for documentaries
White House Briefings Channel
I have the Klowd TV app put out by OANN, which also has Newsmax, Blaze (yeah, I know, Beck is nuts, but still better than CNN or MSNBC), and a few other channels and music channels. Thank you for that list.
