Have you used any pirate streaming websites? They're pure garbage, bad UX, bad image quality, choppy video. The only reason anybody uses them is the price or lack of legal options
I've obviously never committed piracy - but most of the websites I've been on are better than Hulu or many of the other streaming services because they're focused on user features and not what a product manager thinks is pretty and "modern".
You must be using some awful services because my experience has been that piracy, and pirate streaming services, are better, easier, and more available than ever
I find their UI pretty good and at least they work consistently, I was sometimes pirating shows I had access for free on Amazon prime due to DRM issues, a good example it's not only about pricing.
Popcorn time is cancer for me, I always have issues where I cannot play the video anymore, the loader varies (sometimes it loads fast, sometime slow, not matter the download rate).
I think these problems are probably caused by Electron / some bad JS code but still I fint it frustrating, other than that Popcorn time is a fantastic idea. But I just cannot like their UI / UX.
