Plex has launched a new feature for movie and TV show reviews, enhancing its app's social networking capabilities following a $40 million fundraising earlier this year. Users can now share reviews with friends and friends of friends, building on the previous 'Discover Together' feature. Initially, reviews will be limited to users' networks, with plans for broader sharing in the future. Access requires a verified email, and privacy settings will remain intact. Plex aims to transform from a streaming platform into a vibrant community for entertainment enthusiasts.
