The new rating system will, according to Netflix, tell them "that you like something and want to see similar suggestions. A thumbs-down lets us know you aren't interested in watching that title and we should stop suggesting it to you." Furthermore, "using thumbs helps us learn more about your unique tastes so we can do a better job suggesting stories we think you'll love.", Netflix said in a blog post. The streaming company also claims they saw a 200% increase in ratings activity when testing thumbs rating.
I never rated anything in Netflix. Will the thumbs mechanism get me started? We'll see with time.
