The problem that I personally see, at least with Netflix India, is that finding content is like finding needle in a haystack.
Some time back (last year or so), they were showing IMDB ratings for their content, but not now (maybe a falloff with Amazon since it owns IMDB). Now they try to find similar to what I've already watched, which IMHO does not make sense most of the time. I am here to find something new, not exactly same to what I've already seen. Moreover, I first look up the rating on IMDB of whatever I want to watch, and these days it mostly hovers around (5 or 6) out of 10 for almost all of their content.
PS: IMDB isn't silver bullet, but the user reviews are quiet spot on.
