I think the whole unpopular opinion thing has become a way for people to get people to talk about a topic that they want to talk about without saying “I just saw movie XYZ and thought it was great, lets talk about it in this thread”, which I guess would be kind of weird. Like whenever I search this sub for some 30 year old movie I just watched, only upvoted ones with discussion are either “X movie is amazing, Y was so good playing that character” or “Z movie is criminally underrated. How is no one talking about it?”.
