Prime itself sucks. But everything on Freevee is also on Prime, and that's a gold mine for low budget sci-fi movies from indie studios. And you can subscribe to other channels through Prime which makes it easier to manage your streaming subscriptions. You can subscribe to a channel, watch everything good on it, and then easily cancel and just wait a few months until it has more good stuff to watch. Paramount, HBO, Starz, MGM, AMC...

I like it better than Netflix or Hulu.
