Auto play on the AppleTV is easily my most hated “feature” of Netflix. Like 400 on a scale of 1 to 10.
Also their quality setting choices are weird. It jumps from 700kb/s (noticeably bad quality with a lot of banding and compression artifacts) to 3000kb/s (HD) or 7000kb/s (4K, good quality but slams me up against my 1TB data cap every month). They really need a choice in the 1200kb/s to 1500kb/s range (decent quality, moderate data usage).
