I think 99% of the "hard stuff" at Netflix is serving the video.
Making a robust, consistent, fast user experience that works well across all devices, resolutions, and network conditions is quite hard.
If it was easy then fewer websites would suck.

One thing I found was when emulating mobile screen size I wasn't able to horizontally scroll with my track pad. It works on Netflix though. I'm betting you'll find 100+ of those 'small' things with user testing across different OS/browser combinations.
