"As a Prime member, you can already watch thousands of popular movies and TV shows at no extra cost, including exclusives and award-winning Amazon Originals available in over 200 countries and territories worldwide. Save even more with exclusive deals on video purchases."
No 'extra cost'? All that content isn't free. I feel about this much as I do about cable subscriptions by default including the cost of ESPN and other sports channels:
May I not subsidize this, please?
People outside the US may actually do that, because they don’t get Prime and thus they don’t get Prime Video as a free rider.
Personally I subscribed to it for The Grand Tour alone. For $4 a month, I find that worthwhile.
Prime and Prime Video are available and bundled outside the US.
To my amazement I found a surprisingly big catalog of RiffTrax and MST3K there. Definitely an unexpected bonus.
I do care about the new car reviews, The News, 'what would happen if we made a car...out of spaghetti noodles', on-location shoots etc. GT has its own take on each of those.
