What use is any opinion piece? You're either interested or you're not. You read it or you don't, just like any article. No other utility is required. What use is this post?Good I suppose, that they change their mind. But why even pay attention to critic reviews if they can't recognize a piece of Hollywood history when they see it? Critics like Ciskel and Ebert panned Aliens because "it's about a child being put in danger", while everyone else can recognize it for one of the best sequels and action movies ever made. Then what use are film critic reviews?
I find it interesting to see what others thought of things I've seen. That's one use for me personally.
