I personally don't mind the ads on Amazon Prime because they're instantly skippable and do actually show things I might be interested in. Plus they don't show random shit like ads for a car or a TV or something. I don't sit and browse Amazon (because the browsing experience on Amazon prime is dogshit), so I go straight to anything I want to watch on there. The only opportunity to discover new shows on there is usually from outside of Amazon, or their pre-roll ads.
Also, they should stop showing me ads for things I've watched.
They better not make them unskippable ever.
