In english if I want to ask for someone's opinion of a movie or event I would ask
What did you think of [insert topic]?
or I would ask
How did you find the [insert topic]?
In German I was taught
Wie hältst du von [etwas]?
I think I came across where people use finden; but I am not sure how to use it. Can someone share some common colloquial examples of how one can ask for opinions over any topic?
