Trailer Autoplay — Real Win or Metric Inflation?

Duration
~25 minutes
Difficulty
Medium

Netflix is testing a new trailer autoplay behavior on title cards — when users hover for 2 seconds, a 30-second trailer starts playing. The test shows higher play starts but unchanged total watch time. The team is split on whether this is a real UX improvement that helps users discover content faster, or metric inflation that makes the dashboard look better without creating real value.
